Translation is duplicated

I have installed WooCommerce 2.6.8 and plugins qTranslate support for WooCommerce, qTranslate-X and WooCommerce & qTranslate-X to be able to translate my e-store in 2 languages (EN and MK).

In order to be able to show prices with and without tax and to show the text in both languages, in the backend in WooCommerce>Settings>tab Tax in Price Display Suffix field I have inserted firstly [:mk]/{price_excluding_tax}без ДДВ[:][:en]/{price_excluding_tax}no DDV[:] and later changed to [:mk]/{price_excluding_tax}без ДДВ[:][:en]/{price_excluding_tax}without VAT[:].

Now I have a situation where this string hasn’t been replaced but duplicated and in the English version I have long description as 900,00 ден without VAT/900,00 ден without VAT/900,00 ден without VAT/900,00 ден no DDV.

This long description remains and continues to duplicate no mater what I write in the tab filed Tax in Price Display Suffix. I have tried to delete this string remaining N/A, to write something else, but the changes are accepted only in the Macedonian version and in the English remains the long description???

At the moment at the backend I have only {price_excluding_tax} без ДДВ (without [:mk] or [:en] )and you can see the problem here
