Cannot unload canola at silo

[Millennialplague]

Good afternoon,

I have the Krampe SKS 30/1050 filled with canola. I have been unloading at the sell points with it just fine. When I got enough money I bought the Unia 4 bin silo and it says “Cannot unload canola here!”. Does anyone know what the problem might be?

Is the bin full? Many bins have a maximum capacity which totals all the items in the bin against the bin maximum.
