It says that for ex in arenas 30 premades are availale yet only 2 or 3 will actualy show as if the rest are invisble how can i fix this?

bottom center, premade type selector.  choose the sub category you're looking for, or 'all premades' to show everything.  also, uncheck 'qualfied'

in the top left it shows 'premade (X - Y)' which means there are X premades showing after the filter out of Y total premades

yes yes but the lines are invisible like where there should be line after line theres 1 out of 10 showing i dont know why
 

A screenshot would be helpful. 

nvm it fixed itself
