Hi Viktor, 
Greetings from Syncfusion support.  
We have checked with your query and suspect that the reported issue caused due to incorrect mapping of DropDownList fields or fields API not mapping with DropDownList component when data source is assigned to it. So, we suggest you ensure that fields are mapped correctly with provided data source for DropDownList component. Here, we have prepared the simple sample for your reference and attached it below. 
Still issue persists, please revert us with below details. 
  1. issue reproducing sample or code example of the data source and field mapping part that will help us to check the issue and provide the prompt solution at our end.
  2. Is there your already worked component breaks or newly rendered component having this issue.
  3. If already worked component breaks means, please share the details your current version with old workable version
These details will help us to provide exact solution at earlier
