Weather Alert Doesn't Key

The WSI Weather Alert would not key this morning on the Utah Scientific HD Switcher. Key and Fill were coming out of the WSI box. And they were coming out of the AJA HD DA. Switching the output on the DA to another port resolved the issue. Strangely the AJA DA is now putting video out on the original port that it did not put out before. I don't know, but it worked.
