my fafsa submitted and i got my submission summary back along with other information, but i have a “check back for corrections” notification

hi! as the title states, my fafsa was submitted and i got my submission summary back along with other information, but i have a “check back for corrections” notification. what does this mean? is my form not completely finalized and there will be changes? or, is that for those who may have messed up their application and need to fix something? if anyone knows more about this, i would greatly appreciate some information! :)
