For the past several weeks, I've been having an issue where my first exercise of the day doesn't record in the log. I'll start the routine, do my reps, then click either the "Save & Rest" button or the "save". Regardless of which, 9 times out of 10, the exercise isn't saved. It doesn't matter which exercise I use. If I go back into the exercise, then it will save it. Once the first one is saved, all others in the routine for that day seem to record.

Any ideas? iPhone X, IOS 11.3.
