FS22 Bergmann farm - New BGA built, but no grass, hay etc. can be unloaded into the bunker silo

[The Punisher]

Hello Farmer,

I play FS22 on the Bergmann farm and have bought the building plot (industrial area) and built a 2nd BGA (from Planet) on it. Now I have a small problem with the Planet bunker silo. Although it is designed for grass, hay, corn and chopped material, I simply cannot unload grass into the bunker silo. I always get the message "whole plant compaction 0" in the HUD. And that's the case with every silo that I place on the map. Does anyone happen to have a solution?
