If you updated from legacy add-ons previously from your SLP, the initial distance methodology has changed so if youve changed your center map at it is remembering old settings..
Take these steps
Try changing your center map at to a new address (any random address in PA).
2) Go to Locations / Manage and check that the Initial Distance column seems somewhat sane (10 miles not 600 miles). If NOT , please let us know. Especially if you have the latest version of SLP 4.7.2 and all your legacy add ons deactivated and deleted and new add-ons are updated.
3) Fix your center map address to what you really want.
4) If you want to be sure it works, re-investigate the Locations / Manage and see that initial distance is still sane.
5) Check your map.
