Well I was playing Skyfactory 2 and trying to build an autocrafting system with Applied Energistics 2 ^^. So far so good but fast I realized that the Interfaces were shown as "Nothing" It wouldn't craft.... Now I need your help... I took some pictures.^^

Edit: You have to copypaste the link, otherwise it won't find the album.

Based on your picture, it looks like you only have one interface actually touching the assemblers. The others are just floating there connected to "nothing."
