Imported Members showing as Guest - Empty profile

[RavenDelana]

I'm new to this, so forgive me if this isn't clear.

I had someone import users to my new forum using a script. Those users show up in the system, are able to login and post, but have the following issues:

It seems as though, when they post they are presented as though they are not logged in users.

• On a post, their User Info shows a User title of Guest. So, they are not clickable, the member action drop down does not display, nor does their online status.
  
• They are also unable to edit their profile field such as Bio, interest, location. In fact, when I go to Users>Search Users> they appear in the list, but when I enter their profile it is completely empty.

Is there any way to fix this?
