Kevin "Jack" Haugrud was the acting United States Secretary of the Interior, serving since the end of the Obama administration on January 20, 2017 until the swearing in of Ryan Zinke on March 1, 2017. Until becoming Acting Secretary, Haugrud was deputy solicitor of the Department of the Interior.
Hagrud was deputy solicitor of the Department of the Interior after becoming Acting Secretary.
It says "Until becoming Acting Secretary, Haugrud was deputy solicitor of the Department of the Interior." "until" means that he was deputy solicitor up to that point, then stopped. I think the system had difficulty with "until".
