Can not edit transformation of text

Hi, I would like to ask you. I have a trouble how to change the transformation of text in Woocommerce. I make a simple product and the headline H1 is capital letters. The same is in checkout page. All products and info are in capital letters. I do not know where to change it. You can take a look on my website. I have a theme oceanWP and Elementor.

Thank you!
