Thanks for your reply and advice.
I have deleted the phone App and its data, I have also cleared the cache on the browser as I am using a browser (safari) to run Quickbooks.
I know the phone version isn't compatible with CIS deductions. When I look at the audit history "line 4" or what would have been CIS suffered has been deleted "*previous row 4 deleted" shows in yellow highlights.
Bank value in quickbooks seems to be correct but CIS is now missing the two respective amounts.
