Garmin coach: benchmark run not registering - and therefore not providing other workouts

I did the benchmark run for a garmin coach plan - it shows in my activities in connect on the right day, but somehow is not synching with garmin coach. Garmin coach seems to still be waiting for me to do the benchmark run, and therefore isn't populating any of the workouts. Can I/you make them synch, or somehow manually enter it? I don't want to waste another day.
