"There are too many art xml files in the project. There should only be 1."

Idk if this is the place to post this, but i need help with a bit of a modding issue I've run into. Basically I've made a custom civ, and now the only error message I'm getting is "There are too many art xml file in the project. There should only be 1." I'm new to Civ6 modding, and I have absolutley no idea what's causing the problem and how to fix it, but clicking on the error message isn't redirecting me to the issue. Any help would be welcome.
