Trouble getting smart fasteners to work with Assembly

Hi Folks,

Its probaly been answered before but I am new to all this so not sure off terms extra to look for an answer to my problem.

I have a slotted plate that will distribute axial load from bolt to plastic flange face and through to the base aluminium where the fastners thread into.

I have tried many time with out success to get smart fastners into it.

I was trying to put M5 Socket cap screws with narrow washers on the top stack.

Am i doing something wrong or is Solidworks not capable of doing it in my feature setup?

I appreciate you taking your time to look at this.

Thanks
