Bug in To do's - Due date won't change unless you go to "Other..."

Another bug: The "No Date" option doesn't work properly. I have a smart mailbox set up to show all items dated plus/minus a year from now (i.e. all dated items) and four undated items showed up in the list. Selecting "no date" didn't work, so what I had to do was use the "other" option to set a date a couple of years back then go to iCal to set the items to "no date". That cleared them from the smart mailbox in Mail.

I am having the same issue. I can not change the due date to anything except "Today" unless I choose "Other...". Tomorrow, Next Week, or Next Month don't work.
