The version you are showing does not exist. When I visited your site it was showing a version of SLP from at least 6 years ago.
We do not have an add-on called pro.
I cannot recreate your issue. If you wish to update to a current version of the plug-in, Log into the SLP account in the versions and download the current SLP version. I do not know if it will be compatible with the rest of your plug-ins if you have not updated them as well. As far as not geocoding, you would have to look at your Google API key and make sure you have the right kind. They changed billing multiple times over the years and again on March 1.
Alternatively you can switch over to the SLP SaaS. Read in documentation the pros and cons.
