Group related band(s) visible, but the corresponding grouping expression not assigned

Group Header band(s) or Group Footer band(s) are visible, but the corresponding grouping expression not assigned. In this case, the group related bands of the corresponding levels will not be printed. For example, Group 2 Header or Group 2 Footer are printed only if [Report].Grouping Expression 2 was assigned.

Grouping expression assigned, but grouping features never used in report

Some of grouping expressions was specified, but Group Header band and Group Footer band of the corresponding grouping level are invisible and the grouping level never used in Expression objects. For example, you specified [Report].Grouping Expression 3, but forgot to set [Group 3 Header].Visible and [Group 3 Footer].Visible to True and never used grouping of the third level in your Expression objects. Please note, that specifying grouping expression will cause calculating its result for every database record in the report, and thus will slow up the report generation.
