Macros Organize

Trying to reorganize my Macros. Managed to remove some folders that were empty, which is what I wanted. But there is one entry that has nothing in it that I wish to delete. Seems to be on a different level to what the others were. Same level as mymacros.
See screenshot attached.
How do I delete this line? Have tried looking at the options but the ‘delete’ button stays greyed out.

That is a file you had open. Macros can not only be in your library=profile, but also contained in files.
Unless you close that file, ther should be no need to “delete” that place.
