Cannot create User group: Error - invalide property assign_filter

I’m having the same ISSUE described here:
Cant’t create usergroup because of invalide property assign_filter · Issue #2784 · Icinga/icingaweb2-module-director
And that seems to be solved… BUT even if I’m with this release still have the problem:

Any suggestion?
P.

It is fixed with the next release the bug is in 1.11

  • FIX: UserGroup creation failed since v1.10.0 (#2784)

and there is an even newer release with 1.11.5
