Some models have blank IPC entries created in their medm
These entries show the same model as sender, which should never happen. some of the medm controls are whited out as if the associated epics variables don't exist.
Some examples:
h1iopsush56:
H1:IOP-SUS_H56_OMC_WDIPC
H1:IOP-SUS_H56_SRMSR3_WDIPC
Also h1calcs has three channels
Epics vars in whited out boxes are degenerate with only a few characters, something like "_ET".
