I've noticed another bug reproducible in firmware version 14.17:
I have phone notifications disabled on my watch by default. After installing firmware version 14.17, notifications/messages started showing on my Forerunner version despite these being disabled (through watch menu > Connectivity > Phone > Notifications > Status: Off). So, despite these being OFF, my watch still displays phone notifications. If I toggle this option (turn the phone notifications ON and then back OFF again) it fixes the issue. BUT if I soft-reset/restart my phone, then this bug is back (notifications are set to off but still displaying on the watch). Fully reproducible.
