All bank reconciliation gone haywire

I have five accounts running on cloud. All of them now show the field “reconcil” clear instead of the green colour. They all have the wrong reconciliation date, i.e. not the last reconciled date.
e.g.

this one shows reconciliation date 31/12/2014 whereas I had reconciled to 21/05/2015. If I change date to 21/05/2015 and click on reconcile and enter figure I get this message:-
. Please note that I get this same message on all the five of the accounts I have… It says it doesn’t agree with the balance but in every case it does.

Thanks. Should be fixed now.
