Power Apps Studio no longer recognizes some formulas...?

[Stacey_T]

I'm not sure of the problem I'm having or how to troubleshoot it, hoping someone here can provide some guidance.  

I have a PowerApp built for a SharePoint List where the list in its entirety has maybe 100 or so fields.  Fields are shown/hidden based on a dropdown value in my PowerApp. 

The "save" icon also has a formula for DisplayMode where If(ddRequestType.Selected.RequestType="A Certain Request Type",Edit,Disabled).  

The save icon no longer shows/hides in Power Apps Studio based on the request type, it just shows disabled all of the time, although it used to work at one point.  It does seem to work when the App is published, though?  

Creating a label with text = ddRequestType.Selected.RequestType just says "blank" regardless of the request type I select.  

Another Power Apps user says my form is inefficient and it probably is, but will it literally not function the way I have it set up?

Has anything changed with this control: ddRequestType.Selected.RequestType; what's its Items property?

[Stacey_T]

Nothing purposely changed, no.  It is the second value of a cascading dropdown where

Items = Filter('Intake Request Types', IntakeQualifier = ddIntakeQualValue.Selected.Result)

[zmorek]

Hmmm has anything changed with the column "RequestType"? Are you getting any errors anywhere?

[Stacey_T]

No errors (surprisingly!), just what appears to be a loss of functionality in the formulas...  I need to delete one of the available RequestTypes but haven't done so until I can figure this out.

Something seems funky, for sure! Have you tried creating a new dropdown, inserting the same Items() formula, then adding a text field to see if it recognizes that dropdown? 

[Stacey_T]

I tried creating a new dropdown for RequestType just now (so Items = Filter('Intake Request Types', IntakeQualifier = ddIntakeQualValue.Selected.Result) but it is still saying the value is "blank".
