Stealing my chips?

I have 172 million chips total... I buy in at the 400k/800k blinds table with the max that it lets me which is 160 million.... I buy out with 172 million after
Playing.... Then I go to check my chips and it only says I have 175 million total chips??? When really I should have 184 million!!! This happens every time. FIX THIS!!!!!!
