Weird Calendar sync issue

[blazr2k]

My calendar was working fine yesterday. Now for some reason it won't display my one time events on my Work calendar. On the same calendar I have events that repeat and they show but it won't show my daily work schedule. I tried adding a new one time event on the calendar and that came through with out any issues but the ones that were on there previously will not show. Has anyone had this happen and maybe know of a way to fix it?

try removing the calendar or account, try clearing your calendar data (setting/applications/calendar storage), then reinstall.
