Cash in my paper account is gone

My paper account had $114331.7 equity in total in Feb 8th, but today, when I checked, all the cash is gone for no reason, only the $28,249.45 left which is my paper account’s stock value.
I do not have any trading or transfer in Feb 9th. Is this a bug or something wrong?
