Issue With Dropdown List From Query Rule

I am running into an issue with a dropdown list that I am trying to add to several process models. The data that populates this dropdown list comes from the database via a query rule for the list of items and for a specific item if it exists.

Here is the relevant information:
Display Label: =append({"--Select Group Tag--"}, pv!groupTagList.name_txt)
Value: =append({""},pv!groupTagList.GM_Id_int)
Default Value: =pv!groupTag.name_txt

pv!groupTagList is populated from all of the active tags in the database
pv!groupTagList is a cdt that contains an index (GM_Id_int), a name for the tag (name_txt) and some other values
When storing this information back into my cdt for the form I store the id rather than the name since names can be modified but ids will remain unique.

The problem that I am experiencing is that it does not matter if their is a non-null default value when I open the form where this dropdown is located I always see --Select Group Tag--....
