Yes, theshizon; thanks for thinking about others reading along.
Great that this is working now for you.
Another “gotcha” with Mixamo is that some information is placed in Takes, and if that was accepted during import but not really recognized, things might behave weirdly. Perhaps here is the difference between the two you have. I avoid typically guessing here, as I find this not very efficient compared to have the file on my screen. With the files, I would know and be able to provide a short answer. You seemed familiar with 3D apps, so I believe you will check this.
My best wishes for your project
