I'm hoping someone can help me with this issue I'm having. All contributions on the Dashboard and Find Contributions screen have the exact same date and time for the Received date and Thank-you Sent date. Attached is a screen shot. The top has a Thank-you Sent date of June 18th, 2017 12:00 AM and the second does not have a Thank-you Send date set. I am currently running the site on Amazon AWS Linux with Drupal 7.55 and CiviCRM version 4.7.20. I am getting the "missing indices on some tables" performance warning and try to Update them but it errors out in the logs.
How do you fix this? I looked at the CiviCRM demo and the same issue is happening. Is this a bug? or is it just me? This is a screenshot of the html on the Contribution Dashboard page, the second receive is suppose to be Thank you date.
