What might improve this print is to apply some adhesion to the glass plate.
A small amount of glue, hair spray or tape.....

The issue is that the nozzle is pressing up against the plate causing no filament to be extruded due to no space between the two, not the part sticking to the plate.

Is the issue always the same in the same location?
I am wondering if the glass-plate itself may not be flat enough to be compensated well by the compensation algorithm.
If the area which is printed too close to the bed isn't close to any of the bed measurement locations, then this would also hint at the glass plate being very un-flat.
I think you might be right. Taking the most flat scale I could find I did a comparison of visible light between a desk top and the printer bed. On the desk top, there is no visible light and the scale stays flush with the table when pressing down on either side. On the bed, the scale stays flush on the right hand side of the bed, but on the left a visible gap is present. When pressing down on the left hand side the right hand side of the scale then rises slightly. It is not much, and I wouldn't think that a small gap as such could really throw off the whole algorithm for leveling. Ill see what I can do on the support side of Ultimaker to possibly get a replacement.

Back when I was first trying to solve these issues with the UM support team they did suggest that the bed could be a culprit. Again, I did not think that the bed being higher in one area by at most a millimeter would have this drastic of an effect on this kind of printer. Maybe I am mistaken. If anyone else has had a similar issue and has fixed it by replacing the print bed please leave a comment below.

Yet the "White" material print looks ok.....strange....
