[Known] Bug Cannot Unload Seed from Train

[Bullet2020]

FS19 (Steam install), Windows 10, Ravenport

Loaded seed into train cars by moving seed pallets near cars and pressing R to refill. Put about 20,000L into all cars that can hold seed. I cannot figure out a way to get the seed out. I've tried:
1) unloading with shortcut I and Ctrl+I at all train stations and away from all vehicles and stations (no menu option appears)
2) bringing various seeders close to the cars and attempting shortcuts R and I on both the train and seeder (no menu option appears)
3) bringing an auger wagon close to the cars and using shortcut R and also putting the neck under the train and trying shortcuts R and I on both train and wagon (no menu option appears)

If there is a way to unload seed from the train please let me know!

Thank you
