In the Clubs mode lobby, we can use various toggle features.
There are toggles for selecting match type, as well as the keeper match toggle, the similar squad size matching toggle, and several others.
However, due to the complexity of these multiple toggle options, many users do not fully understand how they function and end up misusing them.
Example
As an example, a YouTuber who specializes in Clubs mode content mentioned in one of his videos that the substitution feature occasionally does not work properly. In particular, he reported that even when the “keeper match” toggle was turned off, the opposing team was still able to substitute their goalkeeper.
In fact, this issue is not caused by a bug in the toggle system.
This issue seems to be related to a situation where your team does not have a human goalkeeper, and you want to play only against opponents who also do not have a human goalkeeper while still retaining the substitution feature, then there is currently no way to achieve that.
Because 'keeper match' functions only during matchmaking, it doesnt affect ongoing match.
To completely prevent the opposing team from using the substitution feature, including goalkeeper substitutions, and using human goalkeeper, you must turn OFF “Enable Join Live”, turn ON “Match Join Live.”, turn ON the 'keeper match', and not have human goalkeeper in your team.
Btw users also mistakenly interpreted turning off “keeper match” as a feature that prevents them from facing a human-controlled goalkeeper on the opposing team.
