Fleet battle - a DRAW!

The fleet battle stats show a draw then reverted to the galaxy map, automatically continuing in "don't show fleet battles" mode where my surviving ships destroyed the final Thalan ship. We deserved to win, we fired more shots! I had another draw later in the same game.
I called my ships "Galleon" because they were slow but heavily armoured medium hulls; I had acquired some advanced armour technologies, that made this 88% armour/12% attack design relatively cheap.
