nsn has a point in the comments: you are paying the full fare now because since the changed return journey is very close, the promo discount doesn't apply anymore.
As described on the relevant page, emphasis theirs:
If you want to have your ticket reissued and get the discount again (limited to the number of special offer seats on each train), the new journey date has to be at least 5, 8 or more days away (including the purchase date and up to a maximum of 60 days in advance) from when it is reissued.
...
Outside these periods and conditions, the ticket is reissued for a ticket without discount and the difference in prices will be charged.
Note that this doesn't explain why you saw a different number on the site.

Thanks for replying. I got the refund. They take the whole amount that is 86.40 for two ticket and refund the whole ticket price of my old ticket that is 67 euro for two person to my account. This is the way they operates. Appreciate your valuable comments.
Thanks,
Sudip
