I installed two new Bontrager tires on my MTB SE6 front and SE5 rear. I went out for my first ride this evening. The tires felt awesome for the first half of the ride. I approached an off camber rock roll that I have done dozens of times and as I began rolling into it, the front tire unseated, burped sealant, and I crashed. I rode out of the trails without issue. The tire sidewall has a bit of damage (photo) but still seems to hold air fine. Hoping I don't need to replace it.

 I've never burped any tire like that before. I'm not sure if my tires weren't properly seated or if I just got unlucky.. I used a hand pump to set the tires up tubeless. Using the method of setting the bead manually with tire levers as much as possible. While inflating I didnt hear the classic POP I have previously with other tires... pumped them up to 45 - 50 PSI to make sure. Inspecting the tires the bead looks properly and evenly seated the whole way around. 

Looking for opinions on the sidewall damage, no pop on the bead during setup. And to top it off I also lost the rear brake lever bleed screw and didn't notice until I got home.. Hopefully those are available locally. Would it require a bleed as well?

Thanks in advance.
