Could you provide versions of Plugins and any other SLP add-ons if you have any , as well as your theme that you have and/or site url and which WP version?
A screenshot is best for these purposes. SLP 4.5.05 works with WP 4.5.xx
Do you have Network Active Multisite WP configuration by any chance?
And you do or do not have the User Managed Locations add-on for SLP?
Once we have this info we will be in a better position to assist you
thx
