Another newguy question, this about vacation.

My vacation was prorated slightly, so I bought days from the bank to bring it to 2 full weeks. iCrew shows them, but when I try to split the days and do a secondary bid, it tells me I can't do that since I don't have at least 14 days.

Any way to do this, or do I have to bid all 14 days together? Can't get through to Vacation planners in CS -I'm sure they're busy as one-armed paper hangers. Mentor is out of country I think. ALPA PBS guys the next folks to call?
