2x Same VST

I’m having issues with using 2 instances of the Digitone VST; 1 for my Digitone and another for my Digitone Keys.

Overbridge seems to forget which VST is assigned to which device. Unfortunately there is only a single VST for both devices (ie: there isn’t a Keys specific VST). Any ideas? Is this an oversight? A bug?

I notice there are 2 unique VSTs for the Analog Four & Analog Keys.

Thanks
