In recent experience, when purging remittances you can't actually choose a specific range of remits to purge, it just does everything that's been printed (to my knowledge). So I was hoping to purge really old remittances and ended up purging all of them. I think a range feature for purging remittances wold be really handy.
Also midway through realising it was purging everything i pressed cancel, but it only stops it up until the point it was at, by which time most remits had been lost.
