Red ship no course change after detecting enemy verified

I did observe many irregularities in the Syrian PTG boats in the A Passage to Lebanon scenario, apparently Syrian boats don't abandon their original courses even after detected enemy ships, but they increase speed to maximum, keeping their original courses, don't approaching enemy ships.

At last in this second scenario I did get the pretended effect (And of course is no checked the "no change course" for red ships in the Miscelaneous AI Settings).
After some 3-4 hours of gameplay, Blue ship is detected, and Red ship accelerates to 28 knots as in pursuit of Blue ship, but without course change!

And now, Red ship is going south at 28 knots, just to running aground in the Egyptian coast!
The game is of very difficult play now, in consequence.
