Administration page button shows link after updating from enterprise to standard version

hello all,

I updated our Xwiki from enterprise version to standard version. Everything works well. But the administrator page is strange. I can see all hyperlink of the buttons on this page. Could you please help me check it and give some advice?
xwiki

I would start by cleanup the browser cache.

Then you should probably check customizations of the standard flavor and revert some of them: go to Extensions -> switch to Installed extensions -> search for XWiki Standard Flavor -> click the arrow next to Uninstall -> “Compute changes”. This will calculate a diff of the whole flavor between the standard version and what you actually have in your wiki and you can revert any document you don’t think contains valid customizations (some are valid like XWikiPreferences, the home page, etc.).

@tmortagne thank you, sir. I tried the method you gave me. But it didn’t show any difference between them.
I viewed the code on the website console. The buttons have some invalid code. Please see the picture.
Can I edit them in the server? Do you know the location?
