Can’t reload a part

I’m trying to reload a part with FUNC + CUE or even FUNC + PART and then RELOAD. It always says „part reloaded” but I can still see an „X” on the right side of a part when i open part menu with a PART button.

I see that there are some unwanted changes I could get rid off if I could just only reload a part.

Have you saved the specific part before? Otherwise there is nothing to reload and it stays in its current (modified) state.

Yes, I have saved it many times. Besides it usually warned me about a part that has not been saved previously.

Could you elaborate?

I think I lost my scenes setup. There are no transitions I put there before.
