I added some income and expenses as bit of a test it let me select the Category but when I displayed the transactions they where missing from the list.

Can you tell me any more details that can help me replicate the bug, such as what category and payee you selected?
Scratch that, I found the problem. I will put out a bug fix release shortly. Btw if you find any more bugs its better to post them in the feedback section where issues can be tagged with a status.
