Hey there!
This was an issue with the base game biobaler in an earlier build (when I made the mod), looks like Gaints have finally fixed it now.
Seems they changed animations and also broke some other values that this mod used, it should be up to date now if you download the new version and replace the zip file it should work as it was meant to! I also took the time to lower the drop mechanism a bit more so hopefully the larger bales don't catch as easily when being dropped
If you have any more issues please let me know. Cheers and happy farming!
