Remove activities, City percentage unchanged

I had a few runs from several years ago that partly went through the city I’m currently running. I have decided that I don’t want them to be considered by CityStrides, that I’ll run those roads again. I removed the activities from my Profile, and the LifeMap now shows those street un-run, but the percentage completed of the city hasn’t changed. It was 82.52% before I removed the activities, and it is still reporting the same.

Is this expected? Thanks.
