Politics I imagine. Everyone knows that dog-leg they perform is for a reason, and that is so as to not fly over Sri Lanka.

Australia has a 10% share of NovaSAR 1.

"Australia is one of the world’s largest users of satellite-derived data, but most of that data comes from foreign satellites. That’s why, in September 2017, we announced that we’d secured a 10 per cent share of tasking and acquisition time over the next seven years on NovaSAR-1."

To my mind, there are a few possible reasons for the missing Sri Lanka.

For one, that display is apparently a legacy system that has been in use for decades, and back then they might have thought depicting Sri Lanka in close proximity would clutter up the render of PSLV flight path.

Secondly, they may not have wanted to spook the Lankans into thinking that the rocket is flying dangerously close to the Sri Lankan landmass or its territorial waters. That map is after all quite zoomed out, so it may have given such an impression even if the flight path was sufficiently away from the danger zone. If the Sri Lankan government had expressed concern, Indian govt and ISRO may have ended up having to convince the Lankans, or even alter the existing flight path of the rocket. Just my conjecture.
