Firstly forgive me if I am asking a stupid question.

I have recently been asked to 'tidy' a badly administered set of books for a client using Sage Accounting (Cloud). I am also new to Sage.

The bank account on the systems has (as far as I am aware) never been fully reconciled and there are a huge amount of incorrect/duplicated items.

I decided to start my rec from scratch and "unreconcile all the entries" 

After entering the statement date, balance etc. I have manually ticked the entries but when I reach the bottom Total Paid/Received is showing as zero and the difference is still the closing balance of the statement.  I am hoping that I am missing something very simple and have not broken Sage lol! 

TIA
