AutoCad 2D :: Layout With Numerous Plot Numbers

I have a layout with numerous plot numbers, they have there own layer, they have a consistent style and height but display differently. According to properties the only thing that varies is their content and x,y location. It should be a 2d dwg but i have had 'issues'.They have consistent layer properties, linetypes, weights, the font isn't bold, colour etc. I have tried flatten, flatz, specifying them at a significant height and then bringing them down again, match properties which interestingly will make narrow text bold but not the other way, setting Z to 0.000000000001 etc. I tried viewpoint etc and nothing has made any difference.
