As you can see in the pic. Trying to hit the "smart pipette" button, when you are using pY beacons, fails to actually find the beacon, and therefore makes smart pipette fail completely. I presume because despite the am/fm combos all being different entities, they all need to converge to only one signal for selection in a shopping list for "diet beacon".
I'd also maybe suggest that if an item fails to be found, the smart pipette just ignores THAT item, and finds the rest. Rather than failing completely and making smart pipette impossible.
