Incorrect Expiration Date in Login Reports

I updated PMPro to version 1.7.1 and I noticed that in the login reports page there are something wrong for user plan expiration date.

I had a user with the previous expiration date of 12 August and he extended his account for another 15 days so the expiration date in the user edit page was 27 August but in the reports page it was still 12 August. I tried to update the user info through the user edit page of WordPress but still no change in the reports page.

Just to let you know about it.

Thank for your great plugin and good support.
