TablEdit Question - Repeat without Marker

Hi, I am fairly new to TablEdit but have actually been able to put down new music rather easily and quickly. I understand how to insert Repeat signs :| and remove them or change them with their associated markers. However I am puzzled by a REPEAT sign as well as an END sign both of which do not have markers. I would like to remove these but cannot figure out how to do so.

I could not find anything in the manual to shed light on this either.
Any help will be much appreciated.
THANKS
Chris
