Odd shading on model

I’m having difficulty figuring out what is wrong with my model. There are small shading issues on a couple of parts of the model, and I am at my wits end as to what the problem is. I checked the normals, and I don’t think there is any hidden geometry that could be the cause of the issue.

It does seem like you have some interior edges in your model, but the main issue you’re having can be solved by clicking “clear custom split normals data” in the object data properties tab:

That was it, thank you! I’m confused as to how I had custom normals in there.
