The rules for auto relists have changed since Simple Delivery ' came into power' !
It only applies to infrequent and brand new sellers. So when an auction ends now, you have to manually relist it, and it does count towards your 300 free listings per month as a Private seller.
You are up to 199 listings now, so be aware after your 300 quota is used, you will be paying 35p a non refundable listing fee, for each relisted item.
Most of your items in my humble opinion, have a ' ceiling level' for price. You can list those in a Buy it Now format for the price you wish to receive. Those automatically renew every 30 days if unsold, and those relists, do not count towards that monthly 300 total.
