Group ownership wrong in pycharm terminal

linux terminal in a Ubuntu 14.04 Virtual machine says:

user1@new:~ $ whoami
user1
user1@new:~ $ groups
user1 sudo www-data bdlprod mapr rstudio_users

pycharm terminal says:

groups
user1 sudo www-data bdlprod rstudio_users

So group mapr is missing !!!

Any ideas why the linux group ownership is different in pycharm?
