Are you saying the EFC per FAFSA was very different for two kids who will be in college at the same time? And different amounts for the Pell because of that? If so, you need to check your FAFSA entries very carefully. Make sure you indicated two in college on both forms, and that all the data is entered correctly. And if you did a tax deferred retirement rollover in 2020, make sure that was correctly noted on each form.
