SP 2007 Checked Out document discrepency

In SP 2007 Doc Library, we created a view that displays only checked out documents by user. However, the user is seeing a different document count than what others are seeing. They see 1261 documents checked out and others see that they have 21 documents checked out. What could be the cause of this? The rule is very simple. Under 'Filter' it has: Show the items when column 'Checked Out To' Is not equal to Blank
