i submit leon b run before other two runs but other two just got verify. is that mean my leon b run has some problem and got rejected?

Not necessarily, I'm not a mod so I couldn't tell you 100% but there are a lot of runs they are backlogged on at the moment so chances are they just haven't got around to yours, Top 1-3 runs will normally take priority in verifying over others.

But like I said, can't say 100% for sure.

I think runners get confused because you'd think verification happens on a first come, first served basis, yet everyday you see runs get verified a day or two after submission while some people have already been waiting 4-5+ days.
