I am having and have been having the same problem. The due date is wrong. The contribution will come out a day early each week. It will not be taken out twice. It has been wrong like that for a long time for me. Seems its like that for everyone. Right now though, the due date is 2 days off instead of one.. Im not sure if this is a new glitch now or what but my advice to you would be to ignore the due date, check and see when it "actually" comes out, and expect it to come out that day each week. Im not sure if they will ever fix this problem as me or anyone else can not get thru to them about this.
