New Calibration values entered in the Settings section are not written to the radio (with Upload calibration ticked)

[BruMcD]

The current CHIRP release can clearly read and display calibration values and save them to a CHIRP .img file for items including Power levels and reference Frequency correction

I tried
I attempted to do both power and frequency changes (reasonable /required) with v0.22 on the radio,
(UHF band F6 chosen for highest TX frequency /largest frequency error).
Saved as a new .img , ticked the Upload Calibration option box (+OK'd warning) and wrote apparently successfully to the radio
No change was seen in actual power or actual frequency. Tried several times over an increasingly wide range of values
Tried factory reset and did it all again, same result.

Work around
Install IJV, make both changes there , verify both on appropriate and accurate test gear .
Re install v0.22 over IJV, Settings a mess; immediately factory reset the radio.
Re-apply my normal menu settings manually and re check:
Both adjusted calibration Settings were clearly still in place
Read the radio back into CHIRP.
The settings I had tried to change in CHIRP now displayed new values in the right places in the calibration table

Conclusion :
Despite the 'Upload calibration' option being ticked it doesn't successfully upload power or frequency changes ?
The table operation seems correct though; as making the changes elsewhere is reflected in a new read from the radio

My immediate radio issue is now resolved via the work-around - But, Did I miss something ?
