Testflight, All apps in the Testflight app suddenly says Tester removed

In my Testflight app I have a number of apps that I test including my own. Suddenly yesterday all the apps started to show 'Tester Removed'. Even the app I made shows the same. I tried to add my build again by archiving a new build and uploading and then re-adding it to testflight. I even removed and re-added my tester. But it shows Tester removed in the testflight app. I did 'Stop Testing' in my Testflight app to no avail. Somebody Please help, I can't test my apps.
