Botanist stopped adding additives to 3 of 4 pots?

Hey,
my botanist stopped adding additives to 3 of my 4 pots.
He did it first, but after a few days he stopped.
I already tried to remove the additives-order from the pots and adding it again, but that just resulted in nothing.
What can I do to fix that?

Make sure he has enough additives to work with and maybe look at the assignments of each pot, maybe a bug deleted some.

I went to check and saw that there still was fertilizer added in the third slot. I didn't think that would interfere, since the first two are on the shelf.
Well... it actually DID interfere. After removing it so only the two I want are assigned, he started working again as intended.
