Hesitation in transmission at speed under 25 mph

I have a 2021 Honda Passport Touring vehicle and my transmission hesitates shifting when I am driving inder 25 mph. I just had it at the dealership where I purchased it and was told the cause was because I had the Eco button on driving through the city. I turned it off and it is still hesitating. Does anyone else have an issue with their new Passport doing this??
