Next to last(%day_of_week) always shows the last(%day_of_week)

Hi,

when I want to select an advanced repeat rule for the 'next to last' sunday, repeat date always store the 'last' sunday. The same for the 'Third from last', etc.
If I want to select de 'first', 'second'... 'fifth' sunday, it works fine, but when the module have to calculate from the last, p.e., sunday, always store the last.

Even when I try to select the last and the next lo last sunday, it only shows the last sunday.

Any ideas?
