Confusion with Coordinates System of objectDetection() in trackerGNN

I have a confusion regarding objectDetection() as we input that into trackerGNN. If I give measurements in this form and specify the field Frame of MeasurementParameters to be 'Spherical'. Then I run tracker and get measurements using getTrackPositions(......., "constvel"). Then I have to convert that into cartesian coordinates for plotting using plotTrack().
But the issue is that I get the same exact "squigly lines" on plot if I dont specify MeasurmentParameters field at all. None other parameters changed (No change in this phenomenon is observed if we change units from theta to degrees).
So either the case is that trackerGNN interprets as x and y measurements at face value regardless of whether I specify it to be Spherical or not. Or there is something I missed. Either way, Please clarify what is going on.

I was actually using inicvkf for trackerGNN which accepts measurements in Cartesian Coordinates only. But this fact was omitted from the documentation of R2022b. In later documentation, this fact is mentioned clearly.
