Dynamic Links not populating correctly

Hi all -

I’ve got a dynamic links table at the bottom of this doctype which doesn’t appear to be working.

I’m trying to replicate what happens in the “Address” doctype, where a link to a customer is added to the dynamic links table, and then shows up as a link when queried.

In this instance, the ‘Link Title’ isn’t populating and when going to that customer and Menu > Links, the link it’s established.

Does anyone know what’s happening here?
