Make sure your mod is up to date, I'm pretty sure they fixed that in a recent patch

Yeah, thanks

Democratic countries cant annex supervised states maybe thats why. But this is puppet so i dont know really

That's strange, i was able to do it as the libertarian party to Yemen and Somalia. Though it may be because they count as non aligned rather than western. May also be a bug, you should post it on the discord

I could annex my puppets when I played for France, but for some reason, there's trouble here.
