Penthouse Apartments Front Door Bug

There is an issue where the front doors of penthouse lots Fountainview Penthouse (City Living/San Myshuno) and Torres Amanecer (Lovestruck/CiudadEnamorada) are not recognized as front doors. I have to use S4CL to change the state of FrontDoor: FrontDoor_IsNotFrontDoor to FrontDoor_IsFrontDoor and also FrontDoorAvailability: FrontDoor_Disabled to _Enabled.

Unfortunately, it resets everytime I leave the lot. The main issue with this is that there is no welcome wagon, and it can cause random NPCs walk into the apartment and make themselves at home. Happens whether or not you bulldoze the lot. Also affects party events where guests take more normal to arrive.

I think the cause is related to the fact that there are no neighbor NPCs in the building, no other doors front/apartment doors to compare it to. 

Tested with and without mods, I have almost all expansion packs. I also tested using base game doors, no CC doors.  This has been ongoing for years, but I've not seen discussions regarding it.
