The analysis machine says "all compounds present" after i inserted some compounds and afterwards when i try to insert my hand(?) the machine contradicts itself by saying that the mixture is not complete.

Is that a bug?
If yes - How can I workaround it?
If no: Thanks my problem (that never existed) is solved. In that case it could be that I'm not understanding something, however - if the answer is "No" I don't need further help, under no circumstances explain anything, just write "No, it is not a bug" in that case

edit: it's not a bug
