Interesting… I don't have a "Mini Pro 5", but I tag photos using a Garmin GPS device and myTracks (Mac) software.
It puts this in the EXIF data of individual slices:
GPS Altitude Ref : 0
GPS Latitude : 38.9059930833167
GPS Latitude Ref : N
GPS Longitude : 1.43622804999722
GPS Longitude Ref : E
GPS Position : 38.9059930833167 1.43622804999722
GPS Status : A
GPS Version ID : 2 3 0 0
And this shows up in the stitched panorama:
GPS Latitude : 38.9059916666667
GPS Latitude Ref : N
GPS Longitude : 1.43622778333333
GPS Longitude Ref : E
GPS Position : 38.9059916666667 1.43622778333333
GPS Version ID : 2 2 0 0
Could your DJI Mini 5 Pro be using different tags for its GPS data?
This is as reported by exiftool. I think it inserts spaces in the tag names for readability.
