Mac Catalyst not respecting Display Name

Having a problem where the Mac Catalyst version of my app shows the full App Store Connect name instead of the shortened name. When I compile it on Xcode and run it locally, this doesn't happen. However, when installing from TestFlight it does.

--

App Store Connect: AppName: RSS Reader

Display Name: AppName

--

On macOS only, it displays as "AppName\ RSS Reader" in ~/Applications/ when distributed via TestFlight.

How can I correct this? An iPad app running on Mac has no issue, its only when I enable the Mac Catalyst build target.
