Conditional text not working with custom field

I have created a custom property in [ Files → Properties… → Custom Properties ], called, “Location_provision”, (no quotes). The type is set to “Yes or no”, and the value can thus be set to “yes”, or “no”, a boolean.

If I add a field to my document called, “Location_provision”, it shows up as, “true” or “false”, depending on the property being set to “yes” or “no” respectively. If I add a conditional text, where [ Condition ] is set to “Location_provision”, “Location_provision == yes”, “Location_provision EQ yes”, “Location_provision == true” “Location_provision eq true”, or substitute “DocInformation:Location_provision” for “Location_provision” in any of the previous iterations, and set [ Then ] to “me”, and [ Else ] to “them”, I always get, “me”, and never get, “them”.

What am I doing wrong? (Am I doing anything wrong?)
