Indian Railways — shabby treatment to senior citizens by indian railways

I tried to book 2 senior citizen tickets online for me and my wife in 2ac in doronto express. It showed 50 berths available (In two 2ac coaches). After making the payment, it asked you are getting berths in 2 different coaches whether you want to book? It happened four times, my amount was deducted 4 times, each time it asked the same question.
Again same thing happened when i tried to book two senior citizen berth 2ac in august kranti rajdhani from nizamuddin to mumbai central. This time it showed 84 berths available but again my amount got deducted and it asked about berths being booked in two different coaches.
I have never seen such a shabby treatment to senior citizens from indian railways. What is wrong with irctc system? Is it malfunctioning? Why senior citizens are being targeted in this way?
Also there is no guarantee that even after availability of so many berths we will get the lower berth. Does indian railways want senior citizens to climb up the upper berths at this old age?
I think indian railways instead of moving forward are going down and down.
