Custom workout transfer?

I have a FR245. For a week or so, I have had a problem transfering custom workouts to my watch.

- At some point in the last week, the custom workouts were appearing only under one "running" activity (for example, they appear under workouts for a regular run activity, but would not appear under the "treadmill running" activity).

- Now, tonight, I am not able to transfer any custom workout to my watch.

This problem occurred a few years ago but had been resolved; it now appears to have returned.

Am I the only one experiencing this problem? It makes my watch essentially unusable...
