Ok here are the files then;

It includes the following files;
enbseries.ini - With exaggerated values between Exterior Day and Interior Day
PILGRIM2.esm - Edits done in this mod allows the detection issue to be seen. Only Fallout4.esm is required to run it
PILGRIM2 - Main.BA2
Save1_00000000M_Commonwealth_000009_20190105202210_1_2.fos - The save file, should Appear as "Beacon Hill 0h 09min" in the load game menu
Fallout4.ini - And just in case it might be related to some .ini settings, I included the ones I used while I encountered the detection issue
Fallout4Custom.ini
Fallout4Prefs.ini
When you have loaded the save game, enter this console command;
fw 1a65e5
This is in the weather the interior detection issue happens, and it happens if you look up and down.
Also to note, this is an altered weather from the included mod. So it might have something to do with either weather records or imagespaces. I'm not sure though as I couldn't find any specific record while removing edits done by the mod, one by one.
