Offers not shown correctly in Loyalty App

I have a problem with the Offers List in the Loyalty App Template.
When I edit the Offers in the Helpers Folder it only displays the costs Label in Simulator corretly.
All other parameters (name, description and image) are not displayed, even on the iPhone 8, they are not displayed.
The OfferCell.xib in Views Folder shows all relevant labels.

Someone an idea? Estimote Support does not respond after initially good support.

I could solve the problem with a little hint from Piotr.

In the OfferCell.xib I had to give each Label, ImageView, etc. a height constraints and in the Main.storyboard adjust the height of the Rows in the TableView.
