How to edit animation sequence in persona

I created a human model in makehuman, imported that to blender and used makewalk to import a walking animation. I adjusted it a bit in blender and then tried to import that into ue4, but for some reason it always gets a few bones wrong, most noticeably the legs, which get rotated by 90° for some reason.

I can adjust the legs manually to the correct rotation in the preview like this and then the animation looks correct, but clicking save doesnt do anything. If i close the window and open the sequence again the legs are wrong again. So how do i save the changes i make in the preview?

I’ve got the same issue, can’t figure it out.

Just figured it out.
To save any adjustment just add a key after making it and click the apply button.
