Weight training rep counter and change type.

I got a FR265 2 weeks ago. I love it, but as I try to use it for wight training I found that on the watch manually corrected values as discarded upon sync.

An on the web page also (syncs from the app), how can this be solved ? 

Another is, is there a way to change multiply set "type" for example, I select 4 set, and change all to "bench press"??
