You have an allocated amount of on-demand keyword refreshes you can use everyday.
If your keywords are stuck on "Gathering Data" or showing "??" like shown below, performing on-demand refresh will also solve the issue.
To refresh a group
Simply click on "Refresh" at the upper right portion of the group.
To refresh all your keywords at once
Click on "View all Groups" and trigger an on-demand refresh at the upper-right as you would do with a single group.
