Component use old version and not updated in other files

Hi! I don't know how to fix it.
The scenario is as follows:
1) I created components, for example a button.
2) I created a bunch of files where I plugged in this library and successfully use it.
3) I updated the background color and rounding values (Variables) of the button.
4) I saved the changes
5) Now I expect that by synchronizing (updating) the files with the library, the changes should be pulled into the layouts, but the changes are not pulled. Moreover, if I copy a component from the library and paste it into a file to which the library is connected, Figma writes that I have a non-updated component in the file and that it needs to be updated. Clicking on update component, the settings are reset to the old ones. I attach a video, I hope someone can help =)
