Check for a CLEAR ALL commands anywhere before the breakpoint. As documented in the help for the CLEAR function:
clears all of the debug breakpoints.
You can resolve the breakpoint issue by commenting out all lines of code that refer to any incarnation of CLEAR that encompasses CLEAR ALL. There are a few CLEAR commands that encompass CLEAR ALL such as CLEAR JAVA. See the following URL for more information on the CLEAR command:

Concerning the delayed update of the editor window to reflect that breakpoints have been cleared, it is not possible to have an immediate update of the editor when breakpoints are cleared in the editor.
