Hi @Philipp_Johannes

This happens because in Constellation, Pega is designed to show both a small error message near the field and a summary error banner at the top of the screen to help users quickly identify all the issues on the form. The top banner includes the property name (like the field label) along with the error message to make it clearer which field has the problem. This is built-in behavior for consistency and accessibility, and there isn’t a direct setting to turn off just the top banner or remove the property name from it.

@Philipp_Johannes when a validation error happens, the message shows both near the field and in a banner at the top of the screen. If you only want the message to show near the field and not in the top banner, avoid using validations that set messages at the page level, like using "Set-Message" in activities or Validate rules. Instead, use field-level validation and client-side conditions. If you want to keep the top banner but remove the property name, you can write custom messages without using the property reference like ".FirstName" in the message. Pega does not provide a direct option to hide the banner completely, but hiding it using CSS is possible, though not recommended. The best practice is to customize the message to be simple and meaningful without showing the property name.
