Mistakenly and inattentively, because a newbie, I installed two extensions, I'm trying to remove it. I read on the forum that needs to be removed from the file composer.json - I did it, as well as deleted the flagrow folder, deleted it in the admin panel using the Uninstall button, but when working further with composer or loading another extension, a warning appears


and these extensions are loaded again and in the admin panel they remain, as seen in the screenshot.


PLS help advice, how to completely remove them? Thanks
