I'm having an issue using a Types Custom Field in a parametric search that is used in two different Custom Types. For reference, my two Custom Types are "Branch Locations" and "Account Managers". Each one shares a common select element that has a listing of cities. FWIW, I created the Branch Locations Custom Type first. Creating data in each custom post type appears to work just fine and I see that if I make an edit to the select element (such as adding a new city), it is also shown in the other as expected since they're sharing the same custom field.
My problem is when I'm trying to build a parametric search for Account Managers. I want the user to be able to search for an Account Manager by the city select element. However, the city Custom Field is only available under the Branch Locations list and not the Account Managers list in the "Insert a filter field" dialog box. The field is also confirmed to be shared between the two when I go to the Custom Fields Control screen.
I tried adding the city Custom Field that is listed under Branch Locations anyway but the front-end search didn't do anything. And I did confirm that another field does work with the parametric search for Account Managers.
Should there be any issues/concerns using a shared Custom Field for more than one Custom Type with Parametric filters?
