Symbols and Unattached Notes not visible in MBD Section Views

Can anyone help? When I add a symbol or an unattached note to a sectioned view of an annotation tab, the note and symbol appear in the model tree, but disappear after they are placed. I am running M110.  All layers are on. The screen captures shows a created symbol selected in the model tree and the other capture deselected and the symbol disappears in the view. Any suggestions?
