Savia Customization does not save & publish

Hello. The problem I’m having is that some of the changes I make in appearance > customize do not save & publish. For example colors (trying to change theme main color does not save) and changes to navigation. Would you have an idea on where to look for the issue?

(The site was originally on a test server where all such changes could be completed, so highly possibly something went wrong in the transfer to the final destination)
