TableView cell messing up constraints - iphone

Question

I've a tableView where I present news feed from my Database. The amount of cells right now is around 20 but it will continue to grow for sure.
In a cell I've three labels: Title, Date and a short description. I've set up all of my constraints using storyboards. And the height of my tableView cell is dynamically changing according to the size of my content.
The problem is whenever I load my feed, one of the cells is always messed up. There is a constraint between Title label and date label >=30 so it's always at least one cell that will have a title label with a constant width of 190 (the others are always correctly displayed). If I scroll my tableView up and return back to that cell it will come back to normal but the height of the cell will stay the same (too big for the content).
What can be causing the problem?
Thank you in advance!
Edit:
