The pattern has a bunch of walls that are about 1.5mm thick. So just set your extrusion width to a manual value of 0.38mm. That way you can fit 4 extrusions in each wall (4*0.38 = 1.52mm). Remember that you have 2 extruders, so you need to make this change for BOTH entries on the Extruders tab of your process settings.
If you don't do this, your extrusion width is too large, so it can't fit another perimeter in between those walls. That's why it was using the criss-cross fill.
