Problems with Imitation Manager in 5.7

Hello all!

I ran into troubles getting the IL part of the docs to work in 5.7. The regular manager and recording manager work fine, but if i try to feed the REC_Human into it, the output log tells me that the recording contains no valid training data and will be ignored. There was a change in nodes over the course of time and I wonder if these changes are responsible for the faulty behaviour? I attached the manager in questions here: 5.7 ImitationManager posted by anonymous | blueprintUE | PasteBin For Unreal Engine

Any hints on what to change to make it work as intended is greatly appreciated! If more blueprints are needed I’m happy to provide those.
