Cannot remove global like anymore (!)

unfortunately, after I added the post ID to the shortcode and probably at the same time also activated the global button for post page types, the latter one will not disappear anymore.
Even when I delete the plugin the global like will still be displayed (!!!)
It also doesn’t have to do anything with browser cookies as it also appears in different browsers.

To make it clear: I only want to use the shortcode, not the global function. How can I cancel the global function?
It is really a bit crazy to have something nested in my website that I cannot change anymore…
