Google drive unlimited only shows 15 gb of free space

When you have google drive unlimited the hard drive mount only shows 15 gb of free space. This will always show that, but when I want to copy files to the drive larger then 15 gb windows will not let me saying there is not enough space on the drive.

Hi, you have two Google Drive accounts, the normal one and your business account.
I guess you are using your non business account.
