Smart Fastener don't want my second plate.

Hello everyone,

I am new on this forum, after few mistakes (wrong combinaison Ø holes and Ø for screws) on a machine I am creating,  I try to use Smart Fastener but there is few things I don't understand.

- I created 2 plates (2 parts)

- I create an assembly and I put theses plates

- I create a hole for M8 with the assistant, this hole cross the 2 plates.

- I launch Smart Fastener and he don't recognize the second plate, you can see the washer is inside the second plate (blue)

Solidworks 2018 SP3

any idea ?

Thanks
