MakeMyTrip India — refund amount calculation wrong

Hi,
I booked two trips of tickets for my family on march 15, 2020

1st ticket - booked for 4 members. Total charges = 575.46
Trichy - chennai
Trip date = march 30, 2020

2nt ticket - booked for 3 members : total charges = 424.97
Chennai to trichy
Trip date = april 2, 2020.

The refund amount for 1st trip should be 265 and second trip should be 315. But in makemytrip portal, they are showing wrong refund calculation.
Wrong calculation for 1st trip = 105 | actual amount = 265
Wrong calculation for 2nd trip = 165 | actual amount = 315

Please help me to get the correct refund amount. I will attach my screenshots.
