Huge issue with tap to change background

Hi guys, i got a huge problem that i need to solve.

This is my project so far
In the red square, i go 3 different 3D Rooms, that you can cycle through by tapping on the scren. Each of them is attached to a head binding so they can move with the head (this is visible ONLY in front camera).

Same goes for the green square, i got the same 3 different 3D Rooms, that you can cycle through by tapping on the screen. They have been put in a different obj because these are visible ONLY in back camera, so you can inspect the room freely.

I had to make 2 different "Tap to change" scripts, one for Front and one for Back, and a "disable tap script" on back (for front tap) and front (for back tap). This was needed otherwise the 2 "Tap to change" would conflict and it didnt work.

I also made 2 scripts for hiding the back camera rooms in front and viceversa.

My problem is, in back camera (green square), i can cycle and preview ALL the rooms correctly.
In front camera (red square) i can see correctly only the 1st room, the others are invisible, exept for the particles in room 3 (don't know why).

P.S. This is a time sensitive project and i really need to solve this asap. If you can even contact me directly and help me out i can send you a compensation as well. Thank you SO much for the help!
