Hello,
1) Issue is related to Dokan plugin styles (dokan-pro/modules/subscription/assets/css/style.min.css), not to theme styles.
I added the below code to Theme Options > Custom CSS to display it better
.dokan-subscription-content .pack_content_wrapper .product_pack_item .pack_price {
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
padding: 5px;
line-height: 1.3;
left: auto;
}
Anyway, I would recommend you to contact Dokan plugin support and ask them to fix the issue globally.
2) Contact Dokan plugin support and ask if they have any design layouts for the Subscription plans or any additional plugins to style that. Because it’s not related to theme but to Dokan Pro plugin.
2) c) It would better to choose one of these builders and because using of 2 page builders at the same time slows down the site and may cause another compatibility issues between plugins.
Regards
