7. If you configure the levels by dragging the board icons, you do not need
to deal with Matrix numbers. They are entered automatically. However,
if you enter level configuration data manually the matrix number has
to be specified correctly. The rule is to use the lowest slot number of all
the boards being used for that level. For example, if you want to use
boards in slots 2, 3 and 4 for a level, the Matrix field should be set to 2.
If you want to use only the board in slot 3 for a level, the Matrix field
should be set to 3.
