I am using the latest official 7.20 firmware. Every time I do a strength activity, the number of sets and more precisely the word "sets" appears corrupted when view it in Last Sport widget. I tried this in English, Bulgarian and French and the word was always corrupted. See the attached screenshot.
I saw something about Strength activities was fixed in version 6.54, but there are no details about it. I am not sure if was the same. I can certainly live with that, but it would be nice to see it fixed.
