Trying to upgrade Wyvern boots with Basic tier recipe and start button does not show. All the components are in place and power provided. What am I doing wrong? I have 2 golden apples, 2 diamonds 2 eyes of ender, I draconic core and the speed upgrade key. I have 4 fully powered basic injectors on each side in a cross fashion with a capacitor in the middle for power each provided 25mil RF. I've tried placing the objects needed in various positions in the injectors and I never see the start button to begin. I was able to upgrade a basic injector to a wyvern, but I can't use the basic recipes.

wrong apples
