You're confusing things.
The "Paths" and "Grounds" you're talking about, as well as the "Four Yogas" of Mahamudra, cannot be equated with the Development and Completion stages of Highest Yoga Tantra in an exact correspondence.
The Bhumis are a system of classifying realization and experience.
I believe, and it has been communicated to me by my teachers, that a "Frst Level Bodhisattva" would reside on the First Bhumi. Such a being would have a direct experience of Emptiness such that it was thoroughly established, and not just a glimpse, as it were. I do not believe any of us here is claiming to be at such a state. I would equate your use of the term "awakening" with such a level, and I don't feel any other, lesser, experience would be sufficient to be called "awakening." In fact, such an experience, though we could call it an "awakening," is merely a step on the path to Full Enlightenment or Buddhahood, which is what most folks refer to when they use the word "awakening." Although to our eyes, someone who abides on the First Bhumi would appear to be a Buddha, that person would understand the immeasurable distance between his or herself and the final Bhumi of Buddhahood.
The Four Yogas of Mahamuda is a different system, which explicitly spells out the experiences one can have on this path, and there are correspondences with the Path of the Bhumis. But both of these "systems" are just methods of classifying and categorizing experience.
When we talk about the Paths of Creation and Completion, we're talking about something quite different. These are "paths" in the sense that they contain explicit instructions on the methods used in Tantric practice.
I'm not going to get into details, but very briefly stated, the Path of Creation or Phase of Creation or Development involves generation of the deities and mandala, and is concerned chiefly with uprooting attachment to mundane, samsaric appearance and experience. The Path of Completion, sometimes called the "Phase of Perfection," can be divided into two: Completion Stage with signs, and Completion Stage beyond (or without) signs. The former of the two is where you will find the Six Yogas, while the latter of the two is where you will find Mahamudra, Yugananda practice, and Emptiness Meditation, depending on the system, the teacher, the lineage....
Both of these phases/paths/stages go together, and there are various ways of presenting these. In a sense, they go together and are practiced together. Simply stated, one takes the view of the completion stage without signs as the basis or underlying "reality" of the Development Stage. However, it's also taught that the Creation Stage must be practiced until some stability has been developed, prior to engaging chiefly with the Completion Stage practices. In the Six Yogas in particular, one traditionally "completes" the Creation Stage, whether measured by time, by mantra recitation, or by signs, before one engages in the practices of the Six Yogas. However, attaining stability in the Creation Stage is not the same as an "Awakening" on the Bhumis, much less any correspondence with the Four Yogas of Mahamudra.
So, if you understand all this, you can see that we cannot equate the Stages of the Bhumis, the Schema of the Four Yogas of Mahamudra, and the Two Stages of Tantric practice, as "levels" with any equivalence.
It's somewhat like trying to use a yardstick to measure a cup of flour, or using a measuring cup to determine how long a piece of string is.
