Add To Cart Button Inconsistencies

Dear VillaTheme,

Please refer to this page:
Product 1: https://jerungwheels.com/shop/electric-scooters/hx-x9-plus/
Product 2: https://jerungwheels.com/shop/electric-scooters/5th-wheel/5th-wheel-k1-for-kids/
Product 3: https://jerungwheels.com/shop/electric-scooters/xfh-mars/

It seems like the Add To Cart button is not consistent across the board. By default, I have setup the button to use flex and expand across empty space. However, it seems to be getting overridden for some reasons.

This is how they’re looking:

Product 2: https://prnt.sc/zzbKKtTUr1Ak
Product 3: https://prnt.sc/rwO2tMLR8guR

Then there’s another issue, when the product is added to cart;
– If the AJAX button option is enabled, it only shows a link: https://prnt.sc/Acfy2zIKfDtJ
– If the AJAX button option is disabled, it shows the button properly: https://prnt.sc/cuaPYiLnHivR

What I am hoping is the add to cart button spans all the empty space, and once added, with AJAX enabled, the View Cart button appears on the side using only the space that it needs. Basically, the View Cart would be “expandable” using flex.

Can you assist me on this please?
