One of the system schedules policy interfered with the execution of the other schedules

Hello,

I have simpana 11.36.68 and we have a problem because one system schedules interfered with execution other schedule policy.
For a specific client, I configured the schedule so that a Full backup runs on Fridays, while Incremental backups run on the other days. However, last night both a Full and an Incremental backup started at the same time, even though the Full backup should not have been triggered on Wednesday.
This indicates that a system schedule may have overridden the configured backup schedule.
The schedule policy for this client does not provide the option to include Wednesday or Saturday, which is causing scheduling issues.
What might be causing the issue?

Best regards,
Elizabeta
