Hello @AlisonR727 ,
The way it displays in the landing page footer shouldn't really affect other aspects of your account - for example the physical address in the footer of emails, or what you manually type out in the bodies. Is there some other system you're using where the LGLP's mailing address would be the main one that has to be pulled, as opposed to what's just in your account or in your emails?
That said, our higher level technical team is going to investigate this further to see what their suggestions will be to the devs for updating this automated aspect. They'll reach out to you within the next 4 business days with an update, but in the meantime this is how the footer of landing pages is designed to function.
