Its a bug, reboot your PC
I have had it happen twice in about a 12 month span, both times I rebooted and it was fine.
If it persists or is frequent for you, try a reinstall
EDIT:
Just noticed too, yours is not activated, as a trial or through a full license,
That could be the issue as well. When it is activated through a trial, or key it will turn green and display the amount of days left, yours is clearly not activated and may be also why it is locked. See SS below.
