MYOB Bank Feeds - not splitting in percentages

Hi there,

Since the update, in my bank feeds I have a few transactions that need to be split across two accounts.  Previously I was able to split as a percentage. For example - I have a direct debit that goes out weekly that I split across 2 different expense accounts.  I can usually in my bank feed go to the drop down box, allocate me, categorise, enter category (or expense account), then enter in amount (%) such as 50% and then it will split accordingly.  Since the update when I enter in the amount (%) such as 50% - it keeps putting an amount in the first column - have attached screenshot - what am I doing wrong?? huge thanks
