File names issue

I use the RC2 with the fly app and a samsung phone with the RC-N3 and the LITCHI app

I have just noticed this, I was out flying today doing a distance test of the mini 4 pro using the RC2 and fly app, I then switched over to the samsung.

All the recorded files I have from today show this

DJI_20250420185134_0056_D_litchi.MP4

with the only difference being the date time stamp

So why are my files recorded using the fly app on the RC2 being stamped as Litchi?
