Some items in custom fusioncrafting don't show upp. The are invisible. I can't see what the catalyst is, the result or the requred items. Anyone know if there is a fix or this a bug in the other mods?

I mean, you're writing this for 1.10.2, so I'd think that it's unsupported now, but that's up to the mod author.

I suggest you take a closer look at your custom recipes.
