Difference between total assets and liabilities

[AlainCageda]

Hello.

My problem is this:

The result of my Income / Expense statement is say:10 000.

My balance sheet shows 

Registered Gains (or whatever it is in english I'm working in French) : 10 000.00
Unrealized losses (                        d°                       ) : 18.00
                     making my Liabilituies 18€ lower than my Assets.

Anyone has an idea where this come from and a solution to fix it?

TIA
Alain
