Deleting a measure

Hello

These measures appeared but I don't know how, a manip but which one...

I didn't have them, so I don't know how to take them off.

How to remove them?

I am on SW2013

Wouldn't it be an annotation rating?
If you select it and then press delete, does that work?

Oh no, it's a dimension, I can't select it, as soon as I let go of the tracing tool, it disappears
