New Flow Field on Table

Hello all,

I needed to add a field from the Item table to the Assembly Header table so it shows on the Assembly Order page. I created the new field in the Assembly Header table and set the Field Class property to Flow Field and the Calc Formula to Lookup(Item."Work Code" WHERE (No.=FIELD(Item No.))). Then added the field to the Assembly Order page. The Work Code value does flow in from the Item table, but it shows a drill down ellipses beside it, which isn't necessary. Can it be removed or hidden?

Thank you.
