I am half way through a 10k Garmin coach plan and the pace I need to run between has always been visible when I look at the workout. Today it has just disappeared and I can seen no pace for any future runs.

Thank you for this report. To investigate further please respond to the following:
We're following up on the report we received that when viewing your workouts in your Connect app that had pace, cadence, or power ranges, the workouts' targets showed as blank or just 0. We're pleased…
We have enough reports of this at this time. The engineering ticket is being worked and I will notify you all with an update when the fix is available. Thank you.
I just updated to Version 4.69.1.5. Seems to have fixed the issue.
Me too
Pace doesn’t save on one of the steps on my workout on Garmin Connect. Seems similar to this issue <forums.garmin.com/.../1369832, which reportedly was fixed. Perhaps Garmin needs to test the whole workouts feature more thoroughly. 
Edit workout, set pace for step “Run” to 3:30 - 4:30 min/km.
Save and open again:
Pace has been reset to —:—.
