error in calculation of vat due

Hi there. I was digging into why in FAC it was saying there was x amount distributable dividends ij the P&L but at the same time on the balance sheet it was showing a negative owner's equity of 12k. I've isolated this to an error in the calculation of the corporation tax liability and the inclusion of 2008/2009 liability in twice (albeit one is until June 2008).Could you please confirm that this is a glitch?

Also, when digging into the VAT Return, I can't seem to calculate the VAT due at the flat rate scheme percentage. The VAT numbers seem to be calculated at about 12.96%? Any ideas?

Thanks
