Historical data in rank report not matching summary?

[edu-SEO]

I got a new rank report today. For a lot of keywords in Yahoo and Bing it is saying things like >49 etc. When I hover over it, it tells me that these are new keywords for me that I didn't rank for before. When I look at the historical graph for those specific engines though it just shows me going back at the same position historically. For example like position 17 going back many months without change. Can anyone tell me what is up with that?
