Why are my crew pacifists?

[Ruatha]

In a PBW game one of my Frigates attacked a enemy planet with an enemy colony ship in orbit.
At combat turn 8 it destroyed the planet, the colony ship fled for the corder and my frigate parked at the planet for the next 12 turns doing nothing!
The planet was destroyed but the enemny colony ship unharmed, 0% damage.
The ship had "Optimal weapon range" strategy with Firing orders:
"Has weapons, Most damaged, Strongest, nearest".
Do not use type priorities.
Fire on all types (No box is checked to avoid).
Damage percent per ship 80% all else 100%.

It had 2600/3000 supplies after the battle.
The colony ship left and whent 2 sectors away, my ship followed and stopped at the same sector again, but no adittional combat.

The original orders where "Seek after Colony Ship R1, Move to Mu 10,5", AS it happened the colony ship went to Mu 10,5 where the alraedy colonized planet was, propably to refuel, then headed out.
My ship killed the planet, followed the colony ship and had the same orders still in the "Orders window" after the turn.

Why didn't it kill those pesky aliens in that colony ship???
