Nice that you put a video and I suspect that English is not your first language. However, we need more to go on.
It seems that you are stating that your one title box is missing when you preview things. I would suggest that you delete the existing text box and make a new one. Also, review your sizes and margins on your page settings to make sure there is enough room to display the data you wish to see.

Brian's advice to re-create the TextBox may indeed help if there are some special settings in the TextBox that disappears.
I noticed that there are actually two issues. The second one is that when you move the TextBox that disappears up in the PageHeader, the other TextBoxes start to disappear when running the report. The TextBoxes related to the issue are in a PageHeader section that by design cannot grow. Hence, if something pushes the items down in runtime, they may remain hidden. I suspect that the issues may be related to this. However, based only on the video I cannot explain the observed behavior. Are there any changes in the report made in the code behind?
Can you send us a runnable report that reproduces the issue for local investigation?
