The easiest way is please create two separate sliders.
Each one for one language.
Create a slider from your primary language: hidden link
Create another slider in your second language after changing your dashboard to your secondary language: hidden link
Now in your translated page, you can select the slider you want.
So basically you have to create 2 sliders for two languages.
Let me know if you need anything else regarding this.
If you switch your language when you on the page using admin bar switcher hidden link you can directly access to your translation page where you can choose the other slider.
but then my languages do not sync anymore
- I do not understand this
- by trying the above solution are you loosing your translations?
In the past, when you changed language there was always a warning that WP would make a copy from that page and so the language would not sync anymore. I would be a copy that excists next to the original. So when you change something in the original, the translated copy had to be changed manually.
