Similar experience-- over the weekend I mounted the tire with a tube and filled it to max psi and let it sit for about half an hour. Then I deflated it, removed the tube (the bead on one side stayed locked), filled with Stan's, inserted a tubeless valve, removed the valve core and inflated with a floor pump. Worked like a charm. Beads popped and everything. Then I took it back to max psi so that when I pulled the pump head off the air couldn't escape fast enough to really deflate the tire, and was able to get the core back in with a lot of pressure left. Aired it back up and let it sit overnight at high pressure after taking a spin through the neighborhood and leaning hard in both directions. Given the reports of burping I wanted to really seat the mother.

To be fair, I was riding standard Butchers, not the SX casing, and the casing makes a big difference. But at any rate, under sketchy conditions this tire had me riding more aggressively than I normally do in the dry. It only packed up with mud a little bit, not enough to affect anything.
I ran it at 25psi. DHRII 2.3 60a in the rear at 27psi.

Running DHF 3C EXO 2.5 single ply on the front. Awesome tires in every ways. Never burp or converting tubeless issue. Only thing I dont like is how difficult it is to pop the bead off the rim (Easton Carbon Haven) so I can add more Stans goo. Requires Gorilla strength and 30+ minutes of struggle just to pop the bead off. I guess it's a good thing. If anyone has similar issue and has a suggestion on how to pop the bead (meaning break the seal) from rim let me know.
The key to new tires with folding beads is to put your whole hand over the tread directly above the valve core and PUSH down as you hit the valve with an air compressor. This helps to push the tire beads against the rim to air up. I've never had a problem with DHF's and that's what I've been running for over 5 years.
