On one of our PC's, the drop downs (like the one shown below) stopped working. We tried loading settings from a machine where it was working without any luck. Only difference I can find is the version of Excel on this PC, which is 365 Business,

v. 1908 build 11929.20752, working machine has 365 ProPlus, v. 1908 build 11929.20708.

Is there a compatibility problem here?
