Checkboxes instantly reset

Hi everyone,
since the last update i got a problem with changing any parameters like uv channel etc.
For example when i put 1 in the uv channel picker of a static mesh it just instantly reverts back to 0, same thing happens with pretty much anything i tried so far.
When i change any checkboxes inside the material editor it reverts as soon as i compile.
Anything i am missing here?
thanks in advance
