How to remove the error: please assign a section view initial volume

It’s working fine for the Archviz Explorer’s default map but gives the same error on every new level created. I added a trigger volume, named it “SectionView_Initial_Volume,” and then added it to the section view of the BP_Explorer_Pawn. But the message “please assign a section view initial volume” is still showing. Do you have any idea how to fix this issue?
