CHIRP

Using latest daily CHIRP. Radio is similar to the MTC radio UV-5R-3, or the Radioddity UV-5RX3 or the uv-s9. Model UV-860 tri-band.
3+on shows "3B5Rv01".
6+on shows "190831M".
Initially, I misread the radio's memory and then programmed it as a Baofeng UV-5r model.
After that, I got a bug with scanning, you can see more in the video. https://www.youtube.com/watch?v=YlzPtpSBUxk
Every time I try to change the frequency of the UHF band or turn on scanning, it immediately goes to the VHF band at a frequency of 130 MHz or even to a random value.
Also I can not enter a frequency in the range between 200-260 MHz. Although initially it worked, before programming. In this case, the channels work normally in all three bands. Then I found an error and again read and programmed as radioddity uv-5rx3 but it did not help me, no matter how I tried to change the settings for limiting the frequency range. Even if I try to program the original img file, which I first read as uv-5x, it still doesn't help.
