1) What version were you converting from and 2) can I get a copy of your config? Sorry for the late response, I was watching the SpaceX launch.Edit: I believe I found the issue. I'll wait a bit longer to get your config so I can test it on the patch to make sure it actually has fixed the problem.

I also Have this issue

Yeah, I assumed so as it's mainly from the upgrade from v2.1.10 to v3.*.*. Will release a new update.
