From every level league, 4 teams will play CL. Only 32 teams are required to form a CL, meaning that when the number of leagues is 8 (or a multiple of 8), there can't be any problems. At most 28 additional teams are required to complete a full CL. It's more fair to let some teams ending 5th play CL to complete the CL, like they do to complete leagues with #8 teams.
