Blue levels have floor plans created of them, anything blue in revit is a link or editable so it means you can double click it and it will take you to that floor plan view. Don't worry it will print black. The grids will only show however far they extend up the building. So go to an elevation view and stretch your grids up to your highest level. Note you will see a little 3d or 2d next to the grid, if it says 3d then you will be stretching your grids throughout the building. If you only see 2d you are just modifying the extents of the tag in that view.
