Quantity Picker Skipping Numbers

Hi all, I've got the quantity picker set up on my product-grid (on my home page), as well as on my individual product pages. 

The quantity picker works fine on the home page, but in the individual product page, it increments by 2 each time when you click the + button.

Looking through the theme.js file, I can see the function which executes the increment (qtySelectors). Is this increasing my number by 2 on the product page because it is double counting the numbers from the home page when the global settings first load at the home page?

I thought this was the case initially, but then I tried a workaround by changing the individual product page to use a dropdown quantity selector, and nothing changed. The page still shows a button based quantity selector which is weird.

Here's my page for reference (currently set back to button quantity picker): https://naturalbrews.sg/

I'm using the Brooklyn theme.

I've also added code snippets below of my existing page. Any help or direction is much appreciated!

product-grid-item.liquid

  This snippet is used to showcase each product during the loop,
  'for product in collection.products' in collection.liquid.

  A liquid variable (grid_item_width) is set just before the this
  snippet is included to change the size of the container.
  Once the variable is set on a page, all future instances of this
  snippet will use that width. Overwrite the variable to adjust this.

  Example
    - assign grid_item_width = 'large--one-quarter medium--one-half'

{% endcomment %}

{% unless grid_item_width %}
  {% assign grid_item_width = 'large--one-third medium--one-half' %}
