Not saving marker information if lat/long not set

Hello,

From what I can see the plugin is not saving the marker informations/settings if the longitude/latitude is not set, so if we want to keep some informations in those fields before adding the long/lat on save the fields are emptied(Advanced marker settings and the marker). Can you please make sure that the information added in those fields is saved even if the long/lat is not inserted.

Thank you.
