It's all about the Software

Hello Simon,

I have a marker I set the other day Horizontal Net (incorrect frequency) left of the second marker that will not delete from the program not listed in the marker organizer. I also have a second Horizontal net (correct frequency) listed in the marker organizer. How do I remove the first incorrect Horizontal net marker please. Screen shot provided.

Ribbon Bar, View, Markers, Configuration.

Thank you, Simon.
