Disabled plug-ins from 2.1.3

In the screen-cap below, I’ve clicked the `Show: Disabled´ mode and see a bunch of 2.1.3 functions that I don’t believe are on the HD anymore. Is that possible?

Please advise on what’s going on and what to do about it. Running 2.2.1 now.

Also… what is this plugin and where did it come from?
