Explore trying to send ghost update to watch

I've recently installed Garmin explore to manage my courses better for my Garmin epix pro. 

My epix pro is on the latest firmware, but Explore is always trying to "send a software update" even though there isn't one available. Lately it happens mostly when I work out (during the running activity). 

Any clue on why it's happening and what I can do to stop it from happening? 

Thanks!
