How to make 'Products' page without 'CART (0)' appearing?

Existing Business account with Rally template: When I add a 'Products' page (for training, development, and future use) to my existing site (www.taitdesign.com), in the 'Not Linked' section, and with the page not enabled, "CART (0)" shows up in my navigation bar. I don't want the cart to appear until the page is active. It may not be active for weeks/months.

How can I 'turn off' the visibility of the Cart in the navigation bar while the 'store' is in development? I've currently deleted the Products page to keep it from appearing which is pointless.

Test: I did open my site on a different computer and different browser (not signed into Squarespace account) and "CART (0)" was visible.

Sidebar: If one were to sell photography on one's Product page and send the order to a 'fulfillment house' to print, frame, ship to, and invoice buyer — can anyone recommend a few services? 

Yes, you can hide it in the Style editor.

Rally is a variant of the Brine template. You can hide the cart in Design > Site Styles. Go to HEADER: LAYOUT and then change Cart Position to Hide.

Thanks. I don't know how I missed that. Simple enough. Thank you.
