Comment 10 for bug 1667853

I had this problem too. It is completely impossible to self-discover the solution to this problem, due to the poor UI design.

The developer probably wanted to have the feature of adding text to the indicator, but implemented it in such a way that users can't really discover how to turn it on or off, and usually only do so accidentally, eg by removing the extra line in 'indicator items' list (it is not apparent why that line exists; it looks like a bug).

When this text started appearing, I thought that it was some array-length bug where n+1 items were being shown in the indicator instead of the selected number. It didn't even occur to me that that would be by design...
