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.

    Any thoughts from anyone on this.  I have discovered that it occur swhen I shut down SSDR and CAT, but leave my program (K-Keys) running.  Then many hours later when I restart SSDR and CAT and issue a command to get the frequency from the still open K-Keys program I get a wrong frequency returned.  This continues to happen until I restart SSDR. CAT and K-Keys.
