Multiple Quantities Not Adding To Cart

[Candlewax]

Hi Shopify Community, 

We recently migrated to Shopify and are encountering a problem with our shopping cart.

When customers attempt to add multiple units of a product to their cart, the cart only displays a quantity of 1, regardless of the amount selected. Any advice on how to troubleshoot and resolve this issue would be greatly appreciated.

The Theme is Ella theme. 

I have attached some images below for context.

Hello @Candlewax 
I've checked your store and when I increase the quantity I see some current errors in the Chrome console. Please check this issue. Maybe this one resolves your issue.
