Default Search Results don’t display correctly for the second language

Buna,
First of all I want to say this plugin is awesome and it is by far the best translate plugin which you can use free without major limitations. I’m glad that there are still developers who thinks this way!
I encountered a small issue in a website for a client. It is with the default search from the right corner. When the site is in English the search results are fine and displays how it should be, but when it’s on German they don’t display in the right way.
The website is for mobile repair. And in search it should display different titles for specific pages like ( “iphone 5” -> pages about iphone 5 ( iphone 5 display, iphone 5 battery replacement , etc ) in English works just fine but it seems in German it picks random Title Pages.

I searched if anybody had the same issue, and I found a similar ticket where the WooCommerce search was the issue but there was no useful answer for me.

I appreciate your work,
Catalin
