Make previous date metrics (the green and orange lines) appear in reporting

Previous date metrics (prior week, 4-weeks, 52-weeks) showing in total metrics report are not being displayed consistently if using a Customized calendar. They will only work properly when the Calendar is left at its Default setting. The default setting being Sunday-Saturday weeks.

Being in Europe, weeks normally run from Monday to Sunday, so I have to use a Customized calendar which in turn makes it impossible to rely on this very meaningful comparison.
