Potential bug Version 1.4C.2

Potential bug Version 1.4C.2

Hi everyone, the bug that I noticed that could be the cause of many other bugs reported for this version, is the following.
I edit a component already inserted in the block editor, I see the change on the screen, but if I try to copy and paste that component, its duplicate is without the change. It makes me think that the change is not taken.
I attach pictures.

These kind of errors are known. Please search the Community next time.

I had already read that discussion, but it doesn’t seem to express my concept.
I add that I have encountered the problem with both Chrome and Firefox.
