Hello,
First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-)
.
I saw the screenshot you attached and visited your website. The ticket you are referring to the customer was using an HTML block to display the bullets in the list he made himself. In your case you are trying to add bullet points to the product description area.
Please provide with some relevant screenshots of the specific area, from where you added the data in that place to check it myself and help you out accordingly.
Best Regards.
