I'm having exactly the same issue. For example, there cant be any ambiguity in categorising entries under "Interest on bank or other loans". I'm paying Β£35pm interest on a bank loan, and categorise the transactions as such. Of the 5 interest transactions entered, only one of these transactions have been correctly allowed, while the other 4 have been disallowed. This is using Quickbooks Self Employed. This is just one example - other transactions are being allowed sometimes and then disallowed for other entries and have been entered in exactly the same manner. Happy to attach examples.
