I have a UITableView that I\'ve created in a UIStoryboard that has two Dynamic Prototype UITableViewCells:
I believe it has to do with the sizing in Storyboard. It seems now it likes to default to a wider view and most people including me (and judging by your storyboard view width, you) prefer having the width set to 'Compact'.
In storyboard either try setting your width/height to any/any or in the inspector for your labels inside the cells scroll all the way down and play the 'Installed' checkbox and you'll notice it has various options for the sizing class. If it's like mine, you'll have the first 'Installed' one unchecked and a second one for your sizing option checked. I removed the custom 'Installed' and checked the default one and then moved my labels into place.
I don't believe I have enough reputation to post more than 1 image or 2 links, wish I could to explain what I mean easier.
