IPhoto '11 - Calendar not showing imported events

Question

Created a new calendar project, picked the calendars to import into it, everything showed just fine.
I quit iPhoto, opened it up a couple days later, and all the pictures were there, but the events were blank. Nothing on any date. Not even the holidays.
I've done everything to try to get these back.. Unselect/deselect. Trash PList. Create new calendar in Calendar.app. Nothing.
This happened to me last year, and I opened up a bug w/ Apple and received absolutely no movement on it. This year, same thing.
(Last year I had to hand-enter everything into it, even the Holidays.)

Answer 1

Okay, sorta success. I exported my main calendar (which was a local Mac calendar) to my desktop, re-imported it into a newly created iCloud calendar. Picked that from the options tab in the calendar editing view, and the events showed!
... but, once I re-picked "US Holidays" from the Holiday drop-down, my events disappeared.
So, I had to unselect US Holidays to get my calendar's events to show up. (But, this didn't work with a local calendar?)   And then hand-enter all these events in, which now look "wrong", because the imported events show up in the top 1/3 of each date cell, but my hand-entered stuff shows up on the bottom 2/3. (Comon, Apple)
Other things that have worked in the past, which don't work now:
1) When dragging a picture onto a date (for instance, someone's birthday), picking a caption location and typing in a caption - resulted in no caption being shown. If I re-click on the date, the option for caption shows "None". (Possible the calendar type doesn't support it?)
2) Click on a date, hand-enter some stuff into the cell - if I click "off" the entry window, the entry window blanks out, but doesn't dismiss, and it retains the same date. (So it appears you zero'd out all text for that date, which isn't true.)    This entry window should dismiss, I'd think.
