Page layout changed after update

I have updated Highend theme and after the update 2 pages are mixed and overlapping. Link below:

I tried to edit the post (Hilton Malta) again, but I can not save it. It always stays the same (and it is overlapping with the post Marina de Paris). Can you please help me resolve the problem. I can not change the: excerpt, title and subtitle (in general settings), layout (it should be fullwidth) and permalink (this is also wrong, it is from another post).

thank you for your help
