Recipe IDs being

jei:/jaopca/create.material_to_plate.steel
jei:/create/pressing/steel_ingot

Create by default does not add a steel plate recipe, so JAOPCA adds one if possible. JAOPCA does not look through recipes added by other mods to fix possible duplicates, so to remove the duplicate recipe added by JAOPCA, you need to manually disable the recipe by adding "steel" to the recipes.toPlateMaterialBlacklist in the Create compat module config. If you can identify what mod adds the steel plate recipe, I can add it to the default plate recipe blacklist if that mod is present.
