How to delete unwanted markers! Can anyone help?

Hello, Im using Sonar Platinum.  I just inserted some drum replacer kick and snare sounds into my project.  When I did this, unwanted markers began inserting at the top of my project.  Is there a way I can delete all markers with one click or so, so that I can reput markers for just certain sections of my song?  Any help would be greatly appreciated.  Technical issues are deversions of concentrations.
