Duplicate Manifest AppID: OK on 22 jan and tranform to a same existed manifest

Hi in my historical application WF4COOL i used Manifest AppID: EE2AAFF18F474D60981467889E06ADA3

I create WF4COOLSOLID
  • Initial Release: January 22, 2018 with Manifest AppID: d9b344e1-9f01-47d1-a8b8-7be2a55a248f

and now when i want to download a new version on WF4COOLSOLID it says not good manifest id because know it's EE2AAFF18F474D60981467889E06ADA3 same as WF4COOL


What is the problem . how it's possible Who can you change WF4COOLSOLID to d9b344e1-9f01-47d1-a8b8-7be2a55a248f , don't suppress application of course

Thank's

Didier
