Field day cat control issue

When logging for field day using 2 radios both using the club call. Both on the same WiFi. One radio on 40 meters, one on 20 meters. Occasionally one radio would change bands. It seemed to be related to a change made by the second radio. Anyone else experience this? Radios used were ICOM 7300 and ICOM 7300MII. Both laptops were windows 10 machines. We used the cat control desktop app and logged via browser.

@W4JVO In this use case you both need to be using the desktop app and not the stand alone cat control app (now called WRL Integrations app).
