Adding Org Files to org-agenda-files

[daniela-spit]

Am trying to put files to display my schedules using the code below.
I am seeing the schedule from meeting*.org, but those in household*.org
are not being shown in Agenda.

(setq org-agenda-files
   (append
            (file-expand-wildcards "~/02histr/gadmin/todo*.org")
            (file-expand-wildcards "~/02histr/gadmin/writing*.org")
            (file-expand-wildcards "~/02histr/gadmin/household*.org")
            (file-expand-wildcards "~/02histr/gadmin/health*.org")
            (file-expand-wildcards "~/02histr/gadmin/meeting*.org") ))
