I think I understand the issue.
The problem is that FC 27 introduced a new Pass & Follow mechanic, activated with L1 + R1 + X.
Since you use R1 for sprint, holding R1 while trying to perform a normal One-Two with L1 + X automatically activates the new mechanic instead.
As a temporary workaround, try releasing R1 momentarily before pressing L1 + X, then resume sprinting.
However, this is not a proper solution. EA should allow players to remap the new Pass & Follow combination independently or provide an option to disable it.
The new mechanic should not interfere with existing custom controller configurations.
