Main Task "Deploy 6 Special Ants totally in all troops"

How does this task work?
I have 3 special in Pro, One, and Two; and 2 specials in Troops Three. All Troops are led by Orange.
Showing 0/6 completed. Tried changing to Green, Blue and Purple, still nothing.

Try to remove all special ants from troops. Exit. Enter and redo. That worked for me.

For some reason the system does not recognise tasks retroactively.
