No i Did not backroll, Will backroll cause lots of bumps on the door like an orange? Or will it cause uneven lines? What should I back roll with?

Backrolling will create a stipple. I would say youre putting the paint on too thick. Ive never used this sprayer or paint but I know that these guns dont like thick paint. Try thinning it more and spraying more, lighter coats. Try diluting a small sample and cleaning your gun out. Spray in on piece of cardboard and make sure youre getting proper atomization. If youre seeing tails or globs of paint, you need to thin more or up the pressure on the gun. Can you swap out the tips on that gun? A fine finish tip will allow you to spray a thicker paint at a slightly lower pressure.

Back rolling done right smooths everything out and creates an even stipple. So it's just even stipple all the way across, instead of airbrush marks and potentially light/heavy spots.
The way I was taught to do it is to roll from the bottom to the top, then back down right after spraying. Overlap the rolls by 50%, don't use a whole lotta pressure, just enough to keep the roller rolling and on the wall.

Bad atomization of material. Those little Wagner’s are straight up awful and yes you have to cut with water because they either can’t spray or struggle to spray most material at packaged consistency.
These little machines are mainly good for spraying solid stains and Semi Trans Stains. Otherwise they just struggle.

Too much paint,& probably too much water. Do 3 light coats instead of 1 super heavy coat. With water-based products you must let the first/previous coat dry completely before applying second/next coat. Looks like solvent popping caused by too much product or not allowing first coat to dry 100%
You may also need to adjust some air/volume settings if there aresome.
also airflow and heat are gonna help dry properly
This. Solvent entrapment causes these Bubbles. Read the can and check the recoat time.
It even happened first coat on the doors, although much smaller bubbles.
Material was applied too thick most likely. This happens if the surface of the paint dries faster than the material under it. As it cures it off gasses and the bubbles form.
Ah I will try to dial back the water % but that does make it hard for the machine to push paint out. The device only lets you control the amount of paint not how much air comes out. I was going thick I was trying to get an even coat such that when light hits the door you don’t see lines.
I hear you. I'd dial back the water as much as possible. And do 3 light coats letting dry 100% before applying each coat
