Have you tried to change the mentioned settings?
I do not see Add to cart button on your shop page – http://prntscr.com/lfchvg you can enable it via Theme Options > Shop > Products style > Product content elements. “Product content effect” allows you to select design type for the products on the shop page. “Product title chars limit” – controls the length of the product title for the products at grid/list, related products, prev/next product navigation.
If you are looking for something else, provide some screenshots for better understanding. You can use such screenshot maker as Lightshot https://prnt.sc/
Also, provide us with temporary wp-admin access.
