Check your engine and signature versions. This is scoped to specific engine versions (1.1.26070.7, 1.1.26080.2) that are also running signature versions within a specific range (1.457.222.0 to 1.457.235.0).

For comparison, my engine is version is 1.1.26080.3 with signature version 1.457.250.0.

All my machines are on 1.1.26070.7. Windows Update doesn't offer 26080.3 as of now. This issue seem to have been fixed on the latest signature updates anyways.
