Multiple ranges causes problems #107

Closed Bobpick closed 1 month ago

Bobpick commented 1 month ago

I tried to add a lot of ranges and I got these kind of messages:

I reduced it down to 3 ranges, and it went back to normal:

I want to have something like this:

is it possible to have this many, and to have a description line?
