What do you mean by "cancels out"?
If you mean the vanilla tank recipe not showing up, it is mentioned in FAQ:
Q: My other mods need the vanilla tank as ingredient, how can I unhide the recipe?
A: If you are first time using this mod on a game, enable "Keep vanilla Tank recipe" option is enough, which is under "Options" → "Mod settings" → "Startup" tab. For an ongoing game, you may also need to check the "Force enable vanilla Tank recipe" option (under "Options" → "Mod settings" → "Map" tab) once, then save game. The later option needs to be unchecked again after activation, because this option enables the recipe REGARDLESS of whether you have the requisite technology.
