Labels switching to another language

I'm not able to reproduce the problem. I'm not even able to switch to a different language, on the site you linked.
Can you please provide more details?

I don't have any multi-language component on my site since it is not a multilangual site.

I was wondering if I can change some labels at the core of Custom Properties. I was able to do so on the ordering options. I would like to so on the text 'Total: 4 results found.'

The string you are looking for is in file:
components/com_customproperties/language/en-GB/en-GB.com_customproperties.ini
at line 15

Solved.
Thank you so much.
