Dual M2 SSD pads placement

Hi,

my Dual M2 adapted has just arrived. It has 2 2.25mm pads and 1 1.75mm pad. How am I supposed to put them? Official guide says the 2.25 needs to go under the module but why did I get 2 of them?

Saw some posts on forums mention that it should go in reverse - one 1.75 under the whole slot and use the 2.25 for the SSD. What are your experience with this placements?

Thank you and happy new year.
