Binding to FormatString and EngUnit in UDT definition tags not working?

I have a UDT definition where I'm passing in parameters for engUnit, engLow/High, and formatString. The low and high seems to be working, but the formatString and engUnit don't :confused: see screenshots below for:
Tag config:

Bindings to the properties:

Binding config example on engUnit:

Not sure what's going on? Interestingly, the low/high bindings in the tag are grey, whereas the other two are black. All are in italics though.

For now, I'll just bind to the UDT parameters instead

Just for kicks, try lowercase "E" and "F" in your indirect binding.

I actually see the same units in the tag browser value too, so I don't think it's that :frowning:
