I need to change the z-index for flex_column to auto

Hello,

we try to integrate a booking engine on the website. When clicking on a date and rooms a calendar/list opens. Unfortunately, the calender is not above the section. So I need to delete the z-index from div .flex_column or set it to “auto”.
But it seams like Enfold “ignores” my css and sets a higher priorities.
Could you please assist?

With best regards
Mandy
