As posted in other thread, I am now facing new issues.
After upgrading to 6.1.1 versiont, I have recreated HTML5 ads, but on campaign tab I am seeing 6 instances of same campaigns, instead of one:

Then if I select one of them and click Save & Close, I am getting the following error:
1062 Duplicate entry '6-326' for key 'PRIMARY'
I have updated attached credentials to this topic. Please investigate and fix.
