When I navigate to:
Settings => Debugger
In the dialog's left pane there is a tree where I see under "GDB/CDB debugger" the items "Default" and "TDM-GCC-64". The Default item's "Executable path" field is highlighted in red because its a path that no longer exists. The TDM-GCC-64's "Executable path"'s field is valid, and working. Just for housekeeping's sake I desire to get rid of the "Default" item in this tree for it is not useful. How is this done?
