The real question is: why are the fills missing?
The answer: poor attribute management.
Try to export the attributes from the blank file, and compare to what you have in this file. Just add the missing fills and all will be well.
Hint: NEVER remove the default fill set, unless you are prepared to go through all the default library parts and check that the fills that you have removed are not used somewhere in any of them.
