Mobility MoCap Pack 1 - 136 Mobility Motion Capture Animations

For some reason, I have to import every single animation after adding the content to the project. Meaning the FBX import dialog opens up etc. I guess this is because they’re not targeting a (the UE4) skeleton. Is there a way around this?

EDIT: Hang on, after cancelling the import, all animations seem to be present. Still a little puzzling…
