SSRS Report expands table width on page 4 only on PDF

My report is doing this:

开发者_运维问答This only happens when I export the report to PDF. HTML view looks just fine...

I am not sure where to even start. The first 3 pages are perfect. It is just page 4 that gets messed up.

Any guesses of where I should look to fix this are welcome.

I've seen this same thing in SSRS 2008 and it was extremely frustrating; it was definitely a weird bug of some kind and not just a page-overlap kind of thing (I turned on borders, and made sure none of the cells weren't meant to expand).

From memory, recreating the tablix from scratch made it go away. Although, around the same time I was updating to 2008 SP2 so you might want to check what revision of service pack you're on, too.
