Net price displayed on first load instead gross price

[agira]

Hi 

 

I have a strange effect:

 

When I load prestashop first time on a browser (browser cache deleted) the prices on front page or any category page displayed is the net price (product price excl. VAT) .

 

When I then just reload or select a product the article is showing as expect the prices with included VAT. After, all pages show the prices correct. It is really just the very first load of a page. 

 

I deleted the smarty cache and forced to compile the template without any result.

 

I use prestashop 1.6.0.14

 

Any help very appreciated.

 

Thanks
