Ableton/Max CV Clock Out with Vst3 flavour of VCV Rack broken?

I’ve added both the VST 2 and VST 3 versions of VCV Rack into Midi channels in Ableton Live (11).

When using CV Clock Out, only the VST 2 channel is listed in the Clock drop down menu. In other words, CV Clock Out does not seem to recognize the VST 3 version of VCV Rack.

I’m not sure if this is a Max for Live problem or VCV Rack, but I thought I’d post here first. ANyone else come across this??
