Does anyone know how to remove Sonic Extensions from Omnisphere?

Simply deleting the specific extension folder from the (Sonic Extensions folder in the) STEAM folder and then refreshing the patch & multi databases doesn't actually remove the Sonic Extension patches from the Omnisphere patch list so I must be doing something wrong.

edit - nevermind - after restarting omnisphere a few times, it seems to have gone. Mods can delete this thread.
