Problem when sending CAT commands to retrieve the frequency from SSDR for VFO A.

When sending FA; or ZZFA; or ZZIF cat command to SSDR I am sometimes getting a wrong response after changing bands.  It does not happen all the time. I am running v.3.1.8.  In the example below I was on 40 meters and switched to 80 meters.  I tried all three commands and got the wrong response.  I have modified a program I wrote years ago to allow for adjusting the receive frequency via keyboard.  All is working well, except sometimes when I switch bands the cat commands give me the frequency for the wrong band.  A copy of my program can be found here.  https://drive.google.com/open?id=1WUboZ2uuyxCBqxWtVnIN9D7g1DGJ_DOk  Just unzip and run it.  If you use it for a little while you will eventually go to switch bands, press the left or right arrow to adjust the frequency and instead it will switch bands.
