Hi @Ivan.1,
In the code yes it is recommended to use the key prop as outlined here: How come having multiple calls to the API to the same content model, or having multiple <BuilderComponent> elements of the same model type, doesn't render as I expect?
The API requests look broken but the SDK is able to resolve them and serve the right content, which is by design, using the key prop is our recommended method to prevent the result caching.
Let us know if you have any further questions. Thank you!
