I had similar problems. I moved to a warmer biome (plains) and it worked.
It could be a biome mod?

Try to reproduce this without any other mods installed. If it doesn't happen, please try to figure out which mod causes it.

Edit: Please try to reproduce this issue in 1.16.x, as 1.15 isn't supported anymore.

Closing this, as 1.15 isn't supported anymore and this issue is stale.
