• [x] I disagree

Reason for disagreement: A warning message should still appear on the application itself. This issue isn't about the fact that the value of the last prefix is taken, it's about the fact that no warning is given when such a circumstance occurs. I think it shouldn't be expected for users to read the entire user guide before using the application.
