World Cup (48 Team, 12 Groups of 4 and round of 32) - Cup Tie Mapping Problem

[Shrew82]

I have amended the World Cup (from 2026) to start with 12 groups of 4, moving to a round of 32.  Obviously the top two automatically qualify, but the best 8 3rd place teams qualify as well.  The file runs perfectly, except for the fact that the cup tie mapping doesn't work as i have asked it too.

I've added the group winners and runners up in "Tie mappings from previous stage" area and i've tried to set the ties in cup tie mapping section to replicate what usually happens, however i have left  8 spaces free for those teams that qualify in 3rd Place (don't know if this is right).  It seems to work to an extent when you test it (not perfectly, but when i've run an in-game test the each group basically plays each other, and the matching in the latter rounds is off as well.

I've attached the file in the hope someone can assist me.  I don't think i'm a million miles away with this either which is very frustrating.
