Adjust customization options across all products in BigCommerce

Currently, we sell 5 categories of products.

https://artisanornaments.com.au/

Small baubles
Medium baubles
Large baubles
Shapes
Stockings

All these products will have either 1, 2, 3 or 4 text boxes for “Word 1, Word 2, Word 3” etc) options on the right-hand side. Currently word 1 is free, and word 2, word 3 and 4 cost $4 each.

We want it so that every word costs $4 and that the first word is no longer free. In addition, there are some products which incorrectly show Word 2 or 3 as “Free” at the moment as well, however they still add $4 to the price.

Another issue:

Majority of H1 headers don't load correctly.
