Hello,
Filters– yay!
For removing the currency symbol- you need to re-name the title for those fields. In the title/label you can also add the info/instructions.
To do that, you’ll need to use these filters: wcv_product_price and wcv_product_sale_price
You create your custom label for your filter. Change the LABEL.
Then you add that to your theme/child theme functions.php
Theme/child theme functions.php:
