Not sure if this exists but I couldn't find anything similar when doing a search in the support forum.
If you open a new chart it defaults to 365 Days back.
If you change the 365 to something less than 365 then every time you look at Format Data Series and then Click OK, the Days Back field will be decreased by at least 1, often more. If you click on Cancel in Format Data Series then this does not cause any changes.
This occurs connected or not and with or without other indicators.
