Catherine, an issue was found, but I do not know if it is your issue or not without more info. If a space was in the name or address WP treated the javascript url differently then what it used to do. We are not sure if it is a combo of SLP 5.0.1 and WP versions 5.0 etc ,
But there is a version SLP 5.0.3 that fixes the address lookup if there is a space or comma .
Please provide specifics and your plugin environment if you are still having a problem
