Help with I2C Addresses on Arducam multi camera adapter

I am using the Raspberry Pi Multi-Camera Adapter Module V2.2 with a Raspberry Pi 4B board.
When I connect the cameras, then boot the Raspberry Pi, then run the command “i2cdetect -y 1” I see that addresses 70 and 36 are in use, which matches your documentation.
However, when I switch cameras by adjusting GPIO pins 7, 11, 12 and then run “i2cdetect -y 1” I see that addresses 70, 36, 72, 74 are all connected, and sometimes 0c.
Is this correct?
I’d also like to know if any pins other 7, 11, 12, 3, and 5 are used by your board?
