In a user test with a blind user the property selection apparently did not work, even though the value input switched to the quantity input?

The error message “Please select a property” was not indicated to be an error message, just as text.

When reselecting the intended property again, the error message went away as intended, but there was no audio indication of that.

When changing the property to a different one, the value type dropdown changes back to matching, but that was also not indicated by the screen reader.
