Engineering Workbench UD field doesnt work

In the Engineering Workbench I created a textbox tied to the UD field ECOMtl.Character01.

In the Engineering Workbench, after loading a part etc, ECOMtl.Character01 is blank. It should not be blank, because a BAQ I run with only the ECOMtl table in it shows that the part I loaded does indeed have a Character01 value.

Why would there be a value in ECOMtl.Character01, but my customization is not showing it when it is bound to ECOMtl.Character01. Is there something in the Engineering Workbench affecting this?

As always, Thanks for the help!
