Hi there!
WooCommerce itself doesn’t automatically set the default product price to 1.00 when creating a new product. Typically, a new product in WooCommerce will have no price set, and it will be blank unless manually entered.
It seems like the issue you’re facing could be due to a custom plugin or code you are using on your site. Could you please deactivate all plugins except WooCommerce and see if you still face the same issue?
If the issue persists, to assist you better, could you please share a screenshot showing exactly where you are seeing the 1.00 price for new products? If you don’t already have a screenshot service installed, here are a few free options: https://snipboard.io.
