UAM and Polylang – groups not assignable?

While using Polylang for multi language support for one of my sites in combination with UAM, I ran into problems with “Locked Recursive” (LR) messages. My user groups have no user role affiliation. The tooltip is telling me that the term post_translations is causing the problem. How can I resolve this issues? Because I am not able to assign new groups to my pages anymore.
