We've noticed some bugs occurring when using a weekly pattern over multiple weeks. At times, the week pattern doesn't apply correctly. We're in the process of releasing a fix.
The fix will be applied Tuesday 24th of October. Once the fix is implemented, you will need to re-check your week pattern (only if you use week patterns over multiple weeks).
We apologize for any inconvenience caused. The good news is that you shouldn't experience any further issues with your week pattern :).
The Waldo team.
