I want to complete Research Module - Energy which needs 8 Cables but I can't complete it.
See the following Screenshot: https://i.imgur.com/TKVF0iW.png

What am I doing wrong?

MC 1.12.2
Forge 2599
Futurepack 26.3.76

#360, #369 - can you please try this version: 26.3.97, it should be fixed there.

Fixed, thanks
