At first, I would like to ask you and your colleagues to not to submit multiple times the same question. It will not speed up any replies, on contrary, people may start thinking you are some spammers.
REgarding your issue - if it occured after hotfix, restore backups and follow the hotfix instructions to the degree and apply it again to see if it makes any difference. If not, install a fresh Kentico instance and try reproducing the issue. If you will reproduce it, share the steps with us - we will be able to reproduce the issue and debug it. Otherwise, we do not know your project and it seems to be related to your implementation and not our product.
I just tested it and it works as expected. Were there made any other changes? Have you cleared the browser cache and cookies? What troubleshooting have you tried?
