SOURCE: Dovetail leave a 'light gap'
This may not be related to your jig. It may be movement in the vertical axis resulting from:
To check the bearings; try routing the cut with a straight bit first to clear the wood for the dovetail bit. Then cut with the dovetail bit (a new one preferably) using very light feed pressure. Is the joint tighter? If so then the bearings are worn. Have the router serviced or replace it.
Check the end-play by pulling on the router shaft, does it wiggle slightly in and out? If so this is your problem. Have the router serviced or replace it.
Be sure the wood is flat and the faces planed parallel, if they aren't the dovetail line will be straight but when you assemble there will be slight end gaps in sections of the dovetail.

I haven't used one for years, but I seem to remember we used to have to dial in the thickness of the planed material just right to get the joints to fit correctly. Doesn't make a lot of sense, particularly if you're using composite boards. And make sure everything is clamped in the jig nice and square, and flush where it's supposed to be.
Also make sure you are running the guide collar right up against the fingers when you cut, maybe take a second pass through. Make sure the bit you're using hasn't been resharpened....Take pains to be sure the bit is centered in the collar.
If you've done all that, I'm afraid you just have to play with it until you get it to work...use some test pieces and you'll see that the depth setting does affect the fit, but they're not as versatile as an infinitely adjustable jig like a leigh. I'm afraid I'd have to put my hands on it to remember and see what wasn't working...
I hope that may help in some way or another...
