Seach company restrictions

im trying to call method
{https://api.company-information.service.gov.uk/search/companies?q=ddd&start_index=0&items_per_page=50&restrictions=active-companies}

It suppose to return list of active companies as far as i can tell, but there are items that do not match that status for examlpe:

"status": "liquidation",

Can someone tell my why restrictions parameter does not work as intended?
