Verification Needed Vendor House Access

[Porky]

So far now I've limited access to my vendor house twice to "friends" . The vendors are on the porch, but the doors are "friends" access only. Twice now, it's automatically changed to "anyone". ?? Other vendor houses I've seen have limited access to the house so why does mine keep going to "anyone"? Is it a glitch, or something else?

Have you customized your house any during this time? That always changes my doors and teleporters
