Subcollection menu appearing twice - how to fix

[JinD]

Hello, I have an issue with a collection page on my site. It's showing the subcollection menu twice. It's not doing it on any of the other collection pages. I've even created a new collection template for it and it's still showing a duplicate submenu. I also tried deleted the collection page and renaming it. Can anyone help me fix it?
