"Next Actions" Stay in Next Actions, Even If The Star is Removed

I had a lot of “Next Actions” (44) and wanted to reduce my list. So, I took the star designation away from about half of them. Then I synced my iPod.

On the iPod this new list remains. Online, the original 44 come back, no matter how many times I remove the star designation. The next time I log in there is my Next Actions list with 44 items. Even if I sync my iPod again anew.

Any ideas what I can do to change this? This is a recent problem and does not seem browser-specific.

Thanks!
