@Alex T⚜️ In that case it would happen with every new event I create, not just with some of them. On the screenshot you can see how it looks when an event is created correctly. Right after that I create another event and when it ‘glitches’, the time is shifted — as if the timezone was multiplied or something like that. Notice that the time shifted is +2.

Dear @LeonidS has my Admin access or I can send it to you if you want to see it in real life. It's completely unusable and we would have to abandon the project, which would be a huge shame and loss for me. Maybe my language has something to do with it because the time format is displayed correctly in CZ everywhere, but on the timeline and in the form it's still in the original.

Thanks for your time.
