Choose activity on Training Calendar.

I have used the watch for over 100 hikes without incident. 

After yesterday's update  9.36 i have this problem. 



I hit Hike in order to do a Hike from my Calendar - Go to Training Calendar - hit Do Workout (which if obviously a Hike)  - and it gives me 'Choose Activity' from a list of Runs!!!!

'HIke' is not an option. Does anyone know how to remedy this?
