Getting Pimoroni 64 x 64 led matrix working with Adafruit MatrixPortal M4

On the Adafruit Matrix Portal M4 I have tried a solder link between ‘E and 8’, as per Pimoroni, and between ‘E and 16’. It doesn’t make any difference, I only get my image split in half across the top quarter and the 3rd quarter of the matrix.

Can anyone please advise.
