Decks C and D are not displayed in the full deck mode even when 4DECK FULL is selected on the TRAKTOR screen display.

Double-click the track display section for Decks C and D (the section where the track name, BPM, etc., are displayed) to switch the display between the full deck and mini deck modes.

The deck display mode set when TRAKTOR is closed is stored and set the next time TRAKTOR is launched.
