I can't reproduce that, it actually also makes no sense! I change the recipe of the inlaid UV lamp by replacing the vanilla lamp with an inlaid lamp. Ingredients of other recipes are not hard-coded by this mod, it just takes the recipe data that are available, multiplies the amount for big inlaid lamps, and adds difficulty. However, I don't ever say anything like "replace electric-circuits with wooden circuit boards".
Actually, I'm surprised you even got the game loaded with K2! Starting the game with just Inlaid UV-lamps, Will-o'-the-wisps, the inlaid lamp mods, and Krastorio 2, the game crashed on start because Krastorio changes the format of ingredients from short to full format. So, my guess is you have some other mod running that reverted the changes Krastorio made and changed the format back from full to short.
Anyway, here's some logging output of this mod after the big-lamp recipes have been changed. I've started the game with both Inlaid Lamps Extended and Inlaid Lamps 2 active together, and doublechecked by also having each of these mods active without the other:
2.353 Script @__InlaidUVLamp__/common.lua:38: InlaidUVLamp: Multiplied ingredients for 2x2 Flat Lamp by 4. (InlaidLampsExtended)
2.353 Script @__InlaidUVLamp__/prototypes/recipe.lua:50: biglamp ingredients: {{amount = 4, name = "automation-core", type = "item"}, {amount = 12, name = "copper-cable", type = "item"}, {amount = 4, name = "iron-plate", type = "item"}}
2.210 Script @__InlaidUVLamp__/common.lua:38: InlaidUVLamp: Multiplied ingredients for 2x2 Flat Lamp by 4. (InlaidLamps2)
2.210 Script @__InlaidUVLamp__/prototypes/recipe.lua:50: biglamp ingredients: {{amount = 4, name = "automation-core", type = "item"}, {amount = 12, name = "copper-cable", type = "item"}, {amount = 4, name = "iron-plate", type = "item"}}
I'm not sure what ingredients you expected to see, but "automation-core" definitely is no vanilla item, so it must have been placed there by Krastorio 2.
