Question about Saws
Usually this is due to debris in the trunion or gear set. Take some time to clean it all out, then use a small amt of oil to lube ways and gears.

Inside the saw, on the end of the trunnion is a stop that is adjustable to zero the saw in to exactly 90 degrees. Either there is sawdust or something accumulated there or it needs to be adjusted. You say you cleaned it out, So you'll need to unplug it an have a look up in there. See how there's a geared piece of steel that moves when you crank the saw over to 45 degrees. Usually there's a bolt or stud with a locking nut on it, either on the trunnion itself or the lower surface of the table top. You need to break the nut loose and screw the bolt in or out to adjust, then crank the saw over to hit it, check for square with a known square, crank it all the way out of the way and readjust, etc. Until you get it right. Make sure to tighten that lock nut when you're done.

User manual for adjusting your saw here.
When you set it up, make sure you check for square to the table, square to the fence, and check square for toe-in or at a 45 deg. angle across the blade from the corner where fence meets table, like you would check a radial arm saw. (hold a framing square with one leg against line of fence/table and other leg against blade and inclined 45 to both table and fence. Make sure all three are dead square.
I never found any way to compensate for the play in the blade itself. It seems like the manufacturing tolerances are a little too loose.
You may need a heavier plated blade. You may simply need a different saw. Those Dewalts are great workhorses, and I love the design, but it's my experience that when you're trying to miter hardwoods of any substantial size there's a little bit of drift in the cut as the blade comes through the wood.
You can try cutting at a slower rate.
I've found that makitas are a little more solid through the cut, though I don't like the general ergonomics as much...
Kind of a pain, isn't it?
Well, good luck.

Follow the blade calibration procedure in the manual.
Take off the back and look at the worm assembly. I think you will find the stop toward the right loose allowing this problem.
If you adjust it (you'll need a 3mm allen wrench) per the manual, it should be fine. I just finished aligning my saw at 90 and 45 degrees and though it is a bit tedious, it isn't difficult.

I don't know why it's rubbing, did you try the small one to see if it is different in some way? How about the stop screw, is it 45 degrees or more? Check it with your speed square. And yes, make a custom plate out of plywood. Which way does the blade tilt? Left is best, locking your work against the fence is the worst idea I have ever seen, (delta) It sounds like the big plate is for a dado blade.
