Crash on load or apply calibraiton data

[mishka-zz]

Hi,

NanoVNA-QT release 20200507 for macOS started to crash on any attempt to load calibration files, or apply calibration data. Previously worked just fine. Device is NanoVNA v2.2, firmware 20200507.

Any suggestion on how to fix that will be very much appreciated.

Gah! I've refreshed the Calibraiton -> Kit Settings menu, and it started to work again! Still unsure how I managed to broke it though.
