[ERROR]: You cannot use this location for auto-loop because it has zero or negative length

Hello,
I get an error every time I open my saved studio sessions. The log window pops up showing this:
[INFO]: LV2: Discovering 272 plugins
[INFO]: Loading menus from /usr/etc/ardour3/ardour.menus
[INFO]: Loaded mixer bindings from /usr/etc/ardour3/mixer.bindings
[ERROR]: You cannot use this location for auto-loop because it has zero or negative length

Does anyone have any suggestions for how I can resolve/troubleshoot this?

I am currently on 3.5.14, but I believe it has been occurring for all of the 3.5.x versions I have used.

halfsoul: somehow the error has ended up in your session file. It is simple to edit this in any text editor. Just open up the .ardour file, search for “Loop” and change the start and end values.

paul: That did it, thank you. I wonder how that error was introduced in the first place.
