residual junk left after deleting themes and topics

Permalink
I just changed themes, from Fundamental to Pixel, and even though I deactivated, and then deleted Fundamental, the blocks remain in the edit menu, with broken icon :( Anyone know how to get rid of them? Presumably, I would need to go into the database directly, which is no problem.

When I look in the System Environment, it also still shows all the themes I every used, but deleted
# concrete5 Packages
Framework Theme (1.7.7), Fundamental (4.0.5), HTML+PHP Code Block (1.0.1), Pixel Theme (2.1.2)

Similarly, I have deleted some topis trees, but they remain in the attribute lists.


Core Version - 8.5.0a2
Version Installed - 8.5.0a2
Database Version - 20181006212400

Thanks
