This still happens to those people aswell, it isnt broken it is just matching with the next person.
As top of my server and ranked top 15 in space time in my bracket I still get faced against the top 3 of the bracket in matsuri, these are people with 20k more BP than me, it happens to everyone.
Only advice I could give you that works for me is to wait until after 9 tails as generally the strongest players go right as matsuri opens.
