Membership 2 Pro - Basic critical reports

We are having issues with members not expiring and/or having the wrong expiration dates compared with the plan they have payed for (paying for one year but having 2 years, etc). It's very difficult to see how many might have issues - we have to look at each individual profile and compare payment history and amount with expiration date.

This would be so much easier to examine with some basic reports. It would be ideal if it could be exported as CSV as well as viewed online with ability to sort by column.
