This issue arises because Production Editor does not have access to submission stage, but when selecting a file type, stage related policy checks are made thus resulting in a authorization failure.
A short term solution suggested by @Vitaliy-1 is to have Production Editor automatically submit as author, instead of production editor, when creating new submission, thus, granting access to the submission stage.
