Three “Quantity Selection” Buttons on Page?

Hello,

I’ve installed the Boutique Theme as a page plugin for my Hearty Theme on WordPress for our Non-Profit Page, Gravity Water. I’m trying to set up a store and have been able to configure most of the editing via dashboard but for some reason can’t get rid of the extra “Quantity Selection” Buttons on the product page. I believe it may have to do with an issue in WooCommerce but I’m not sure.
Any info that can help me get rid of these extra quantity selection buttons would be greatly appreciated!

Thanks
