Collection label disappears when value is too long

**Describe the bug**
I have a collection named "config" that contains URLs in each field. These are all defined as (string) value.
When these URLs reach a certian length (50 characters) the label disappears from the "Preview" panel on the right.

**To Reproduce**
Steps to reproduce the behavior. For example:
1. Go to an admin interface
2. Provide a URL as a value for a string field that is more than 50 characters
3. look at the preview pane to the right
4. Note that the labels are missing

**Expected behavior**
Labels should be visible
