I'm trying to simply log a strength session and don't care about all the details like exercises and sets at this point. However, they keep disappearing from the log's calendar. Sometimes they show until I revisit the page then they are gone.
I use the strength function all the time and haven't seen any problems, either syncing from Garmin or manually entering them. I just did a test manually adding a strength session, closing the browser and coming back in and it's there in calendar and regular log view. I'm using Firefox on Windows 10.
