Joomla 4 Migration

no, I did not read this post ... I will go to do it

I just wonder why is this happening? . It's nothing urgent, I just accidentally noticed such a situation and thought that it was worth writing about it

of course, I wonder too I will investigate, just please tell me if you have installed it again after the update and if you still have the error or not

Before the update, I uninstalled Page Builder CK, I left the Mobile Menu CK, the update went fine and the pages, after changing the template in Template Creator CK to 4x.
Now I have installed Page Builder CK on this new update and the site works just fine.

Interestingly . All Page builder CK settings go back to the same place, after reinstalling, it is, nothing has changed as if I hadn't uninstalled it at all I even have the Pages library that I created before
