OSX: Reason Rack VST GUI is empty when opening it multiple times

Hi, when i load up a Reason VST instance as an instrument, after i close the window that opens automatically on loading, i have to click the editor toggle on and off once before the editor will open again. It’s like Renoise isn’t seeing that i have closed the editor window manually. But even if i close the editor window by using the toggle button it still makes me toggle it on and off one cycle before the window will open on the next ‘on’ toggle. It’s a bit hard to explain. Something is out of sync somewhere. It doesnt happen with other VST3 instruments.

I’m on macbook pro, osx10.11.6 running Renoise 3.3.1 and Reason 11.3.6

Toggling restores GUI but plugin turns into zombie.
MacOS 10.14.6, Renoise 3.3.2, Reason 11.3.9

3.3.2 crashes a lot, downgraded to 3.3.1.
Reason Rack AU works fine

I just tested and yes, AU version is fine on my machine with the same setup as above (v3.3.1). VST3 still shows the weird toggle behaviour.
