Hello Yao,
We would like to suggest an optimal configuration for the header builder. It is advisable to place two sub-containers within a single container and set it to ‘sticky’. This arrangement will ensure the desired functionality and appearance.
Otherwise, both elements may appear to be sticky https://prnt.sc/j8RS-9W56svb , but in reality, they will be on the same level, causing the card of the first container to be positioned underneath.
To assist you effectively, please provide us with temporary wp-admin access.
Best Regards,
8Theme’s Team
