Credit Card Reconcilation

SUGGESTED

Hello, I have credit card entries in 4-7-5 (Reconcile Credit Card Statements) from a few months ago that have been reconciled and still displaying as an open entry.  I did talk with tech support a while back on the 2014 entries and had a "linking" issue which has been fixed.  My question is if I verified/check off the past cleared entries, will it cause any accounting issues?  I also inherited some entries from previous years that I can't find any back up but do not want to void, any suggestions how to clear those out of the 4-7-5 screen again without causing an accounting issue?   Thank you.
