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.
Reply time may vary from time to time but it is up to 24 hours Monday – Friday. I see that our support answered you 7 November but you answered 15 Nov, the delay is from your side, not from our support side.
Anyway, if you don’t want to limit the title length then choose another hover type where add to cart button appears over the image http://prntscr.com/lj5npr or even create your own layout using WPBakery Gid builder option.
