Cannot custom collision preset with custom object type

Hi, I’m currently using UE 4.10.4 and i have problems with saving a custom collision preset.
I found an older thread about this, but the bug has already been fixed.

I can create a custom collsion preset and it will be added to the preset list. The problem is, when i choose a new custom object type for this preset, i cannot double-click and edit the preset afterwards.
When i restart the editor the preset entry is lost.
I can see a new Profile entry in the DefaultEngine.ini but it seems to be corrupted.
