The "100 new" portion of the error message appears to be related to specific contexts where Cheat Engine has pre-filled memory or default values that the user is intended to work with. In some scenarios, Cheat Engine may retain a previous value (such as "100" from an earlier tutorial step) in the value field, and the error message can become muddled when the software attempts to communicate that you need to either enter a new value or select a different scan type.

This is particularly evident when working through Cheat Engine's built-in tutorial. In Step 3, users are instructed to select "Unknown initial value" as the scan type, but this option only appears after scanning with no value in the Value box — and the tutorial does not always clearly communicate this requirement, especially when there is still a value like "100" remaining from a previous step.
