App not showing deref current location, shows old one

my app has a column, type text that is supposed to show a temporary location as we move a vehicle around in our movement request form. It is set as [CustomerL,F].[Temp loc], and the master file has the correct location, but my other request form that is supposed to pull the correct info seems to be locked on the location of when the original request was put in and not the current changing location. Any suggestions?
Also, I put this in the App Formula field.

You are using a de-ref to pull the expression but the parent table is not refreshes that location info until it’s edited or updated. So each time you attempt to de-ref that location value, it will be the initial value of the parent record when it’s set.
