How to sell seeds (Farming Simulator 19)?

I've been playing Farming Simulator 19 on my XBox Series X for a few weeks! I accidentally loaded the seeds into my trailer! But I have no idea how I can get it out or sell it. I've already tried everything. (I'm playing on the Felsbrunn map.) (I don't want to use any mods.)

You can't sell seeds and these big bags and tanks in general. If you have seeds in the trailer, press Ctrl + I to dump them on the ground!
