Flat numbers in UI about dosage

Probably my mistake. I tested again and it's working well.

Hello, values on the interface are presented with decimals, but there is no way to use them as decimal numbers when using the spinner.

You mean the inventory numbers right?
Those are incremented by 1. Which doesn't make sense to be fractioned, when adding new inventory, it needs to be fast.

Dosage numbers are incremented by 0.25, if you mean these, I'm not sure why it's not working for you.

Could you make sure they are displayed as plain, non-decimal integers?

I don't think GTK has an option for that, so it's not possible.
