Hello,
You will need to limit the length of the product title to align the button on the same level.
Different lengths of product titles can shift the content and cause aligning the content on a different level, in order to fix this, there is the option to set one line-, two lines-, or no title limitation in the Theme Settings -> Product Archive – > Product Style – > Product title lines limit
Please check this manual: https://xtemos.com/docs/woodmart/faq-guides/image-size-content-alignment-product-grid/
Best Regards
