Hello,
First of all thanks for choosing our Theme, we are glad to be you in WoodMart WordPress family :)
1) To enable fix tax for the products. First you need to enable tax from Woocommerce >> Settings >> General.
For Clarification see the screenshot: https://www.screencast.com/t/5czbYehFfv
Please read the article for the complete setup of product taxes on your website: https://docs.woocommerce.com/document/setting-up-taxes-in-woocommerce/
2) I visited one of your products which have some variations and it looks perfectly normal. What do you exactly want to achieve. Kindly share the screenshot by pointing out the specific section and also describe your issue a bit more so I can help you accordingly.
Also follow the documentation for guidance: https://xtemos.com/docs/woodmart/variable-products-swatches/
3) To avoid that forcing capital letters behaviour you can Change Text Transform of specific area, you need to inspect its class and add this code to the Theme Settings > Custom CSS > Global custom CSS accordingly:
Just to set an example for you. I set text-transform to none for the categories heading in header.
.header-categories-nav-wrap .menu-open-label {
text-transform: none;
}
