Minor formatting problems won't prevent your article from being sent out for review. If you have formatting issues, the editor will usually ask you to fix them during the revision stage (if you are invited to submit a revision). Usually you just want to read through the author guide and make sure you follow the requested article format as best you can (like, the order of sections, whether they want the figures in the text or at the end, etc.). We just got some reviews back for an ACS journal and we did a bunch of little things wrong, editor just asked us to fix before we submitted the revision. No sweat.
