the budget marked in blue is what you see in june, obvious because of the dates.
The other budget, marked in red, which I suppose you expected to see in June since its recurring, but you have marked the start/end date as 01-05-2010. You need to give a realistic end date, not a dummy date when you want it to recur.
For example you could have a budget
start date: 01-05-2010
end date : 15-08-2012
recur : 1 month

hope Ive clarified this case clearly. Let me know how it goes.

Ive put a lot of info into the website, far from perfect, but I request to have a read, and if you still find it unusable, please try and suggest to me where I can make it clear.
Its difficult with a day job but I'll be happy to help anytime you/anybody need support to make things clearer.

cheers
