Can't delete unwanted tracks

Cubase 11 pro. I have a project that I brought forward from CB5 and it has a bunch of tracks in it that I can’t see how to delete:
If you can’t see the image they have names like: VST Instruments, Model-E, Groove Agent ONE.
Any idea how to delete these tracks and remove any references to the old VST instruments that used to be in this project? When I right click a menu comes up but there is no option to delete.

Found this:
Devices > VST Instruments (F11) > Left click on instrument > Go to top of column - “No VST Instrument”
Closed. Solved.
