RadxConvert cfradial 2 longitude & latitude bug

[zouihao]

Hellow,
When I try to learn about cfradial2 file format, I use RadxConvert to convert between cfradial2 & cfradial1 format for testing.
I found if use ncdump to check longitude & latitude information of cfradial1, it's correct. (global variables)
After use RadxConvert -f cfrad_example.nc -cf2, the longitude & latitude information of convertted cfradial2 is correct, too.
But if use RadxConvert -f output_cfrad2_example.nc -cfradial let the format back to cfradial1, the both information of longitude & latitude will become 0.

Here is the example file (cfradial1):
cfrad.20080604_002217_000_SPOL_v36_SUR.nc

Ubuntu 22.04
