Gengo and Lazy Gallery problem

I am running a wordpress installation with the Gengo plugin for multilanguage support. Now i tried to install some gallery plugins, but unfortunately those don’t work properly as Gengo adds the language extension to all URLs. Is there any way to tell Gengo certain links should not be translated?

you can see the problem under https://www.studiur.net >> Photographie – the links look like that: https://www.studiur.net/photographie/de/?file=Test/de/
