The baseline grade will not show on the prospect profile at all times. The baseline grade is the initial grade that Marketing Cloud Account Engagement assigns to all prospects before any adjustments are made based on their attributes. The baseline grade is D by default, but you can change it in your account settings. The baseline grade will only show on the prospect profile if the grade has not changed positively or negatively. Once the grade changes, the baseline grade will be replaced by the current grade. The current grade reflects the prospect's fit for your ideal customer profile based on the criteria you have set. You can view the grade history and the grade changes on the prospect profile. For more details -> 111213
