First, you need to post a screen screen shot of the entire chart of accounts page from the Settings tab.
Uncategorized appears because there is an account assigned to that group. There is another discussion on the forum of a similar problem. It started partway through another thread, at this post: Uncategorized accounts in the chart of accounts - #18 by FerhatAL. In that case, the Suspense account seems to have been mis-categorized, which is seemingly impossible. That does not seem to be your situation.
Read the various ideas presented in the other thread. Something may trigger a memory of something you did that orphaned an account.
For any future screen shots you post, it is generally useful to include the breadcrumbs at the top of the window so we know what we are looking at. The little snippets you have shown are not very helpful.
