I am using IP version 1.5.8, I found one bug when I am creating credit invoice against any invoice then in client details total amount seems fine but in Report > Invoice Aging that invoice is shown and also in guest panel it is also showing.
there might bug in older version, because I created one credit invoice before 6-7 month that was show not reflating into total of actual invoice, but I create one more credit invoice on version 1.5.7, it is working fine as it needs to be,
So, I deleted old Credit Invoice and created another one. By this my problem get solved.
