RT Radio acting strange

[yellowjacket]

I ride a 2016 Rt and love the bike. I really like the radio since my 2016 GS has none. I have 10 stations pre set on the RT. The first 3 stations are talk radio / news. At least once a week when I get on the bike for a short ride, the first 3 pre set stations are gone. I pre set them and off I go. The following week, they are gone again. This only happens to the first 3 stations. What is going on?
