Hello everyone,

we encountered an issue when migrating from 4.2.0 to 5.x.x due to changes in the display name format. The new plugin configuration introduces the "Enable New Data Format" setting, which can be switched on or off.

Behavior:

1. Enable New Data Format = unchecked:

   • Display name changes from <AF-Attribute-Name> to <AF-Element><pipe><AF-Attribute-Name>.
   • Example:
     • In version 4.2.0: pressure
     • In version 5.x.x: pump|pressure

2. Enable New Data Format = checked:

   • Display name changes from <AF-Attribute-Name> to <AF-Attribute-Name> {element=<AF-Element> name=<AF-Attribute-Name> type=...}.
   • Example:
     • In version 4.2.0: pressure
     • In version 5.x.x: pressure {element=pump name=pressure type=...}

Issues: The following problems occurred when testing both options:

• Field overrides by name in panel configuration no longer work as expected.
• Referencing fields in standard panel transformations fails.
• Series names changed in histograms, legends, ...
• ...

Expected Behavior: We expected Enable New Data Format=unchecked to keep the exact display name format from version 4.2.0 for backward compatibility.

Was it intentional that the unchecked option differs from the old format? If not, can this be fixed in a future patch?
