DMZ Black Mous Always Listening bug

[DawgPoundMBA]

I've competed the black mous always listening mission and selected the option to see prior missions but it won't show up for me to deselect. Thus I always see it as one of my 3 the missions. How can I deselect this competed mission?

I also need this answered, leaving comment in case someone sees this.
