I think this problem occurs because of the position of DRS line (which is the same as the finishing line). You could try to put DRS line a little bit before finishing line and see what happens.
Minor details just so happens that the drs line for that car is past the start finish line, that is why it got drs on lap 3.
If you watch closely enough at the end of the race on a lot of other tracks also, you will see different cars have the finish line in different places. Easy fixed with a spot of fine tuning at a later date.
We're aware of this and why it happens, and it's a long story why it's taking so long to address. But to make a long story short, we need to finish a new track builder tool (for private use by the developers) before we can fix this. At the moment we don't have the power to revise the tracks and fix such things, due to all the changes in the system and things which were not left behind by the original sim developer when he departed.
We thought we had it ready a few weeks ago, but the tracks it was producing had some glitches. So, it's something which is in development but unlikely to be finished for a while, so the situation will probably remain like this for a few weeks at least. Some higher priorities are coming first such as viewer development and stability.
I can only apologise for the wait on track-related issues like this, but we will get there.
