User Defined Table Magnifying Glass

SOLVED

Hello, 

We have added a UDT with a list of fees, and we are wanting the magnifying glass icon to show up so the user can click on it and see the list of options. Currently the magnifying glass is not showing up. Is there a trick to getting this functionality? (below shows we have done this before, but the field below it isn't acting the same way)

Thank you!
