Just noticed that sometime in the past few months a change was made to the Activities report where the number of hikes and miles were merged into one data field with a “/” between them. They used to be separate fields. When you export the .cvs file to Excel, if the number are whole numbers that are also month/day numbers, Excel converts the data to a day/month format. Suggest either defaulting data with one decimal or separating the columns again. Keep up the good work.
I have reported this to the developers
