Nauticam CMC Lense with Flatport Flip Diopter

Hi,

I´ve an Nauticam NA-NEX7 Housing and an 72mm Flatport. On this Port i have the M67 Flip Diopter Holder. Now i ordered the Nauticam CMC Wet Lense and it doesn´t get on the Flip Holder. The Adapter for the Lense didn´t work and do i need another Adapter?

Saw this Adapter

and do i need this one?

The Adapter from the CMC doesn´t work on the Flatport

Thx for your Feedback
