It is possible to get TScore class definitions into a state where DMT displays 6 e-judges and scores them as 4 from 6 instead of 3 from 5.
THis will happen if you manage to leave the HD flag set for a DMT class, either by copying/pasting within a class definition file, or by swapping disciplines of classes in the Class Editor.
In the class editor, when DMT is chosen as the discipline, the HD check box is hidden, but may still be set.
To fix this, edit the offending class, switch its discipline to Trampoline, uncheck the HD box, switch back to DMT and save it.
You should also ensure that the Max e-judges is set to 5, not 6.
