Payroll reversal - bank wont reconcile

Back in March there were 2 payruns that were reversed in one of my clients files (so 4 transactions to balance) All paid from Che account, all cash payments , All dated 29/3 
I can not get the bank to reconcile whether I tick one of the reversals in March or leave it ureconciled in March to balance then try in April.  It consistently is showing there should be one more payment of (eg) $1000 which is incorrect. 
How do I fix this?
