When two ways have different directions JOSM shows a popup. I assume you once pressed "Cancel" in combination with "Remember choice".
Please search for combineway in the expert options and reset these two options:

message.combineway-reverse	true
message.combineway-reverse.value	-1

Now you should see the popup again.

Some GUI in the preferences to view and reset these "Remember choice" settings would be nice.

I think the problem is that one can hit this accidentially. If you select "Remember choice" and think again about it you might click Cancel to revert that "remember choice" selection. Instead you cancel the conmbine action and your this is remembered.
