2 or more of the same vst effects and weird things start

Hi. I’m sure I’ve read about this before but will still ask if there’s some solution for it as it gets quite annoying. When im using more than 2 of the same vst effect on 2 differnt channels the knobs on the “second” one stops working.

I close the vst window and reopen and it works again. Happens on quite a few plugins but especially on camelphat.

Is there a solution for this?

Is this with every VST or is this with a specific VST?
Are those bridged plugins? (In that case that is very odd, unless the VST works with temporary files to store specific data in)

Happens on quite a few, all of them 64-bit so no bridged…

Its pretty weird, yes.
