Shared tabs collating incorrectly

When i add a number of items to my shared tab with my partner, everything is fine until the last stage. Say i add £200 of transactions, it correctly shows me that, and the fact itll be 100 each once i proceed. When i proceed though, every item shows at 200 and splits 100 each way, instead of that being the total. So - if it was ten items totalling 200 - once added to the tab all 10 items show 200, and my partner is told she owes me 1000, rather than 100.
