Problem VAT cs-cart 3.0.1

Hi,

I ain a little problem with the VAT



VAT french = 19.60 %



if the VAT (demo store) is starting off, the French VAT (On) is not calculated



if the VAT (demo store) starting ON then VAt (demo store) calculed



if the VAT (demo store) starting off > VAT is visible in the product configuration





an idea ?
