Failing to engage generator at pre-set levels

Issues began after downloading latest software version on 11/23/25. Set to come on @ 20% and turn off @ 40% but auto came on @ 25%. Also display showed as “open” while genny was running-usually shows as “closed” during this. Apologies in advance as I’m a non techno senior so pl keep responses simple! Off grid system. Cloudy days so auto was needed. Thx.
