For the second currency combination pricing displayed wrong when added a specific price

[ascket]

Hello,

 

I am using PrestaShop 1.6.1.4. I have 2 currency in the store. For the default currency (EUR) I had a problem, like in this topic https://www.prestashop.com/forums/topic/524192-combination-pricing-displayed-wrong-when-added-a-specific-price-for-parent-product/. This bag I have successfully solved thanks to the forum.

 

Since I installed the second currency (RUB), i have the same problem, but only for RUB.

 

Does anyone know, how to solve this bag?

 

Product for example (currency should be руб.): http://steelsport.de/de/muscletech-performance-series-phase-8-4lbs-1902.html

 

Thanks in advance for your help!

 

Kind regards,

Alexey.
