Yeah, the recipes for the big factories are all under the "Crafting combinator recipes" tab. The regular item signals are for the normal, non-50x recipes.
This is unfortunately a problem I can't really do much about, at least not without rewriting a huge part of the code, which I don't have the time for. What I would have to do is check if the selected recipe can be set to the machine (somehow?) and use the next best match if it can't.
Since I would like to rewrite the mod completely anyway, this would be something that would probably make it into that, if I ever have enough time to do it.
I also notice the locale for the recipes and some of the icons are broken. I'm not sure why, but thought I'd mention that I'm aware and will try to figure it out.
