Having an odd issue changing between tool types

I have two monitors, one is a normal monitor, the other is a Wacom Cintiq. Everything works normally on the standard monitor, but obv i do almost all my work on the cintiq.
Issue is, when im on the cintiq screen, holding down on the various tools no longer lets me select between types. So for example, if i click and hold on the fill bucket, nothing comes up. On the other monitor the standard options of paint under, unpaint, etc. come up.
