First of all, I would save/close/reopen the doc.
Then, if the problem still occurs, I would check if its not just a preview bug, hitting twice "W" for instance, to refresh the preview.
If not solved... dunno
I have attempted to save it in different file formats while opening with no luck. Problem still occurs. Hitting W to refresh the preview does not resolve the issue as well.
I had sort of similar bug once.
I managed to resolve it using this trick:
Create a brand new indd doc, with exact same settings than original (size, spreads, etc.)
Change the name of the A-Master page. Name should not be in use in the original doc.
Then copy all pages from original doc to the new one.
Delete first page and the useless Master page.
You might want to give it a try...
I tried but I can't copy the stuff over from the original doc because it just copies the front page rather then the month content. Strangest thing. The pages want to to be there, but the 1st page is always overriding it and placing itself over the other stuff.
huh that is strange for sure...
Does it "copy" the first page when you copy only following pages ?
And what about deleting the first page, then recreate it? Assuming image is imported graphic, it shouldn't take long to give a try...
Meh, I've given up on it pretty much. Spent way too much time trying to figure this out. I've just deleted the copied front pagers and just imported months from another document. It's a shame I could not easily fix this as easily as just deleting a simple layer. Never messed with IDML type of documents before, which the template was given to me in. My guess it was created in CS5.5.
