Weird symbols in Last Sport widget

Just here to report a small bug which does not cause any major problems but it is a little annoying. In the Last Sport widget and when viewing a strength workout, the bottom bar sometimes displays a number of question mark symbols. It should of course only display the amount of sets. I'm guessing around 50% of the times it displays the weird symbols, and the remainder of the times it displays the number of sets correctly. The symbols don't always show up in the same way, and sometimes the problem can be fixed by going back to the Watch Face and then back to the Last Sport widget.

I attached some screenshots for your review. I'm currently running firmware version 14.10, but the bug was also present in the previous firmware version (13.20).
