I just tried what you suggested in the other comment here and renamed the "bar"-indicator to "bar2".

The rename option does not work because internally the indicator maintain the same name (bar), the rename option is only visual.

You have to remove and recreate the indicator with another name.

Worked! Thank you so much :)
