Yes, you are right and I'am fully aware that it should show the items, but somehow it doesn't.

3 things - you did say in the original post "interfaces" but it is worth clarifying and you did not say your items are not crafting so I am assuming that the only issue is the visual one. Also I do not know of, or can think of any reason why, this would be a configurable option or a key bind - what possible reason would there be to want it to work this way!
So ... if you craft an ME interface place it in the world not attached to anything and place a pattern in the patterns section does it just show the pattern or the item to be crafted? If you go to the molecular assemblers and look at the patterns in the attached interfaces (as opposed to looking at the contents of the interfaces via an interface terminal) do they only show the patterns or do they show the items to be crafted?
If it is only through the terminal it may be a cabling problem, its like your actually seeing the patterns as stored content like they would display if you placed them in a chest
However if the problem is universal I would be backing up the game save then removing Reika's mods, that is what you said you think broke it, and see if the problem is gone, if it is then you need to decide if not seeing the item to be crafted without pressing shift is worth having Reika's mods and/or looking at a forum devoted to Reika's mods and surely if there is an issue someone else there would have knowledge of it.
