Detailed Contribution Info Not Displayed
Check that your older financial types have the financial accounts that the system automatically associates when creating new financial types (e.g. income account, A/R account, etc.) - I have see this type of wacky sort of there but sort of not appearance occur when account relationships are not in place. After you add the required accounts, check to see if you see the older contributions on the contributions tab - if not, then it might be a different issue altogether.

Hope this helps!
