Third party Plugins recognised but not in Menu (Maschine 2)

Haven't found anything else on this and have been searching for a bit.

I got some third party Plugins for Maschine 2. After a while or trying and copying and pasting around, I managed to get the DAW to recognise them in the plugins pane in preferences.

But they're not showing up in the menu? I.e. they're recognised but I can't actually select them to play.
