Hi Leonard. That option should be there or at least it works for my PC and phone.
On my PC, if I click on Store a set of click boxes appears on the left that allows me to filter by army, scale, price, color, etc. If you click scale then 1:6 you will only see the 1:6 items which at this moment are just the camera and projector.
On my phone, if I click the menu icon and choose store a filter box appears allowing me to choose the same options as above including scale then 1:6.
Does that work for you?
