My guess as to what the problem is...
It appears the policies are frequency based and allow running 1 time every 7 days:
Saturday_full
SCHED Saturday_Full 0 1 604800
RMR_Weekly_Backup
SCHED Friday_Full 0 1 604800
*** 604800 = 1 week (60 seconds * 60 minutes * 24 hours * 7 days)
If you ran a manual full backup any time during the week, the scheduler would not run another backup until the following weekend (or when a week has elapsed).
If it's not uncommon for backups to be run manually, I would suggest that you set the frequency to something less than one week / once every seven days, but not less than the duration of the window. I.e. if the window is open for 24 hours, make sure that you set the frequency to something more than once per 24 hours, such as once every 25 hours. That will prevent the backup from running twice in a window, and will allow the backup to the due whenever the window opens.
