i just got reached platinum elite and was told that I should remove and re-add my onepass number to existing reservations in order to ensure that I am correctly prioritized as a plat for various purposes.

When I try to remove my onepass number on co.com I can't do it! the system give me an error, and even when I select "no program" from the frequent flyer selection list, it asks me for an account number.

Am I doing something wrong? I've even tried to change the number to my delta skymiles number and it won't let me do that either...
