If you want to turn off debugging, you can click the Graph editor in any place outside the components and the edges, switch to the Properties tab and set the Debug mode attribute to false. This way you can turn off all debugging at a time.

Also, if you have not defined the Debug max. records attribute, you could specify it in this Properties tab (if Debug mode is empty or set to true) for all debug edges at a time. But remember that if any edge has its own Debug max. records attribute value defined, the global value of this attribute will be ignored and that of the edge will be applied.
