Prestashop 1.7.4.2 tax not count

[fitgura]

Hi!

I have a problem with PS 1.7.4.2 as a fresh installed system.

we have only 1 tax rule  should apply to a product, but it not count and not show even in back office and of course front office shows net price.

of course tax rules set correctly and tax switched on!

 

What should be a problem?

 

However, since 1.7.0.0 PS team has no solution for a ,00 decimals, just if hacked the core file :((

 

Thanks in advance
