Statamic 3 - nav filter and max depth issue

I am porting my website from statamic 2 to 3 and running into issues with the nav tag.

I have a toggle field on each page "is_hidden", it is set to true if I want the page not to be visible in the menu.

{{ nav include_home="true" include_root="true" max_depth="2" include_entries="false" is_hidden:isnt="true" supplement_taxonomies="false" }}

the max_depth seems to have no effect and is_hidden:isnt="true" is not filtering the pages based on the value.
