Background - So a couple weeks ago I had a corrupt athlete file in WKO 3 and had to create a new athlete and reimport all of my data.
I wanted to change my FTP yesterday and when I went to do so, realized that the "effective date" section was unchangable. If I changed my FTP it would change it for every ride spanning back to 1980 (the default effective date that I was unable to change)
Any idea how to fix this or why its happening?
