Gate issues in Reaper

In Reaper v6.81 on Windows 11, I have a repeating note that repeats fine the first few times, and then the gate starts to become stuck open so that the note continues playing rather than pulsing on and off. i.e. I can hover my mouse over the gate output of the MIDI->CV module and see that it remains 10v.

This has happened since I upgraded to VCV Rack 2 pro v2.4 from v2.3.

If I load in other VSTs to play the notes in Reaper it works fine.

I don’t see any issues in the stand alone version.

Seems similar to a problem discussed here:
