[How can I take losers from a qualifying round of one competition into group stage proper of another comp?]

Think Champion's League qualifying losers dropping to Europa League. I need to do that in my CONCACAF Champion's League remake. I have central American/Caribbean teams dropping out of the Champion's League via qualifying rounds and I need them to drop into the "Europa League" equivalent group stage. When I'm under Qualification System, I am attempting to add the 24 losers but I don't see an option for that. I'm attaching a screenshot of what I'm seeing. I need teams to drop from "CONCACAF Champion's League" into "North American League"

[Squad Selection for dates outside of domestic season error?]

I'm setting up a revamped version of the top 4 leagues in Mexico. I've set up transfer windows from Jan 1-31 and June 1 - Aug 31 with squad registration windows. I have my seasons all ending on May 15. This error comes up saying I'm not allowing squad selections for a random May date outside of my season. Any suggestions?

[Error in Nation Rules?]

So I'm revamping Mexico's domestic soccer scene by arranging 84 teams into 4 levels. This worked just fine last year, but I'm having trouble now. I test my rules as shown in the images attached to this post. Notice Premier MX listed as division 0 in Nation Rules and Division 1 in Competitions list. I can't do anything about being made 0 in Nations Rules. I can change the number in Competitions List and I've tried everything. My rules for Premier MX get verified if I leave them as shown. However, the minor leagues will not verify the rules because of an issue with the top flight; I find it odd because that league itself is working just fine as shown! Am I overlooking something simple? Just to restate: giving Premier MX a division level of 1 in Competitions List is the ONLY way it'll verify the rules. If I set it to 0 to match Nations Rules, it won't verify.

[Simple questions about editing and the editor - just ask in this thread]

Looking to lower the number of foreigners allowed to be registered by teams in Mexico's first division. Any idea how to do that?
