V2.1 scheduler hard button doesnt work properly

When I use the hard button on learning cards on v2.1 scheduler, the scheduling of cards are somehow wrong.
Just as an example, when this card showed up, I pressed the hard button and it has been scheduled to previous interval which is 3 day.But in the browse section the card 's due is to 5 days later.What is wrong with the scheduling and how to correct it?

Note:I am using anki 2.1.15

Any help appreciated.

Can you reproduce the problem using the latest Anki version?
