Simple Walk showing odd behavior

Hello! Have used Simple Walk for several months without issue. However, as of today it's defaulting to the date of October 25th (it's April 9th) on the watch (Garmin 245) with the time being several hours off. However, it still tracked my walk and had no problem syncing with Garmin to the right day and time. I've deleted and downloaded but still seeing the odd behavior. 

Possessed? :)
