An adjustment (here turning off the time extension after ball 3) already shows the 'off' value, or is changed, but the game keeps behaving as if it were on. Some adjustments also show more possible values than the manual lists.

A setting change has no effect in play: clear the audits and step through every setting

Cause: The settings memory held leftover garbage values that the game used as if they were valid, so what the display showed did not match what the game was actually using.

Checks

• Compare what each adjustment shows against the manual; values outside the documented range point to corrupt settings memory.

Fix

• Clear all the audits, then go through every adjustment and actively change each one (cycle through its values with the start button and back to the one wanted), even when it already appears correct.
