Clip date won't work

Question

I'm having intermittent luck at using the Adjust Clip Date and Time command. I imported some analog tapes so the default date given is today's date. On some of these events, when I select all the clips in the Event and choose Adjust Clip Date and change it, say, to 1989, it moves the event down into the 1989 folder. But I do the very same thing, selecting all the clips by using command-A and visually verifying that all the clips are indeed selected, then trying to adjust the date, it indeed changes the date to the correct year, but it doesn't move it out of the 2010 folder. I've tried changing to different years (1989, 1990, 1991, etc0 but it still won't move the event to the correct folder. Other events move just fine. I tried moving the Event manually by dragging it to the correct folder but it won't scroll down to the correct folder. Any thoughts?

This is a followup to my question above. I called Apple Tech Support and supposedly talked to an iMovie expert. He said that some clips have metadata and some don't. I told him that the clips that wouldn't move to the proper year folder were on the very same videotape that other clips were taken from that moved to the proper year folder. All he could say was that some clips have metadata and some don't.
I can't imagine an analog tape having metadata but that's what he seemed to be saying. I also asked if there was a way I could edit some of the movie data files to fix it and he said no. When I opened that data file in TextEdit, there was a lot of gobbledy-good but also some dates that said 2010. But he said changing those to the proper year wouldn't solve the problem and might make the movie unviewable.
So the search continues for a solution...
