Can I be declined for a receiving an eviction filing if it never resulted in an eviction?
Apparently they can and they did.  You said that the apartment complex did file eviction proceedings against you but that the matter was settled.  Well it made it to your credit report anyway.  If you did indeed resolve the matter with your old landlord you need to go and have them change the report to the credit bureaus - all of them.  A letter written to all of them by you is a good idea as well.  This will stay on your record for a long time and cause you many hardships if you do not take care of it now.  Take charge and make sure that it is done.  Good luck.
