Not Enough Items bug?

[story_]

Okay so when I open my nei menu, everything looks fine. I can see all of the items and even spawn things in. Here's the issue. On certain items (Powersuit capacitors, Forcefield emitter, etc.) I can't press R and get the recipe for it. It just makes the clicking noise. It's happened three times before and I just reinstalled it and it worked fine. But it's been in the span of two days and I don't want to keep reinstalling. Is there a way to fix it?

Try putting yourself in recipe mode so just clicking will show you the recipe. A lot of the items for me will not show their recipes when i click R as that is the sort inventory key. The clicking sound is not NEI but the inventory tweaks doing its job to sort the current inventory.
