Price changes are incorrect

Price changes for stocks are incorrect. I don't know if this affects all stocks or not, but I can see a few that I follow are wrong. For example:

GME. Current price $249.72, up $172.93. But yesterday's close was $147.98, so change should be $101.74.

PBI. Current price $10.33, up $2.80. But yesterday's close was $13.63, so should show as DOWN $3.30.
