Problems with the Editor animation settings

Hello,

Since Unity 2019.4, I have some issues with the animation settings of the imported .fbx file.
For example, when I want to put the animation on loop, I check the "Loop Time" checkmark but after I hit the apply, the checkmark sets back as unchecked. The same goes for the rest of the animation settings as if it does not apply any new change I make there. The same .fbx behaves properly in Unity 2019.2 and 2019.3.
I submitted also a bug report to Unity, but I guess it will take time to respond and I kind of need a quick fix.
Any ideas on how to fix this will be very appreciated.

Thanks

 

I'm having the same experience on 2020.1.8f1. Looping seems to have been disabled on all imported animations and cannot be re-added.

For me this is caused by the Character Creator script as described in the forum post linked above.

 

Having this issue with Unity 2020.2.1f1 also
