Thank you for reporting this. This should be fixed in Animation Rigging version 0.3.0 and on wards. Internally we already ran into this a while back. What version of Animation Rigging are you using?
Hello, which version will be available in unity 2019.4?
Actually i don’t see any upgrade on the 2019.3 unity line (still on 0.2.6) but only in the 2020.1.
