Not working [md-select] shortcode

Hello! Couldnt find answer in forum so making new topic.
[md-select] shortcode is not appearing correctly on my webside.
Here is an example:
https://gotoalbania.ru/en/car-rental-in-north-macedonia/
I guess the problem in my custom css page style or page template but couldnt find a solution how to fix it.
The code in shortcode should be correct:
[md-select label=”Car type” outlined=”yes”]
[select* menu “economy” “comfort” “4х4” “minivan”]
[/md-select]
Thank you in advance
