This thread is resolved. Here is a description of the problem and solution.
Problem:
The client was unable to find strings for translation in RevSlider, even after enabling the option in RevSlider and it being visible in WPML.
Solution:
We recommended creating a separate slider for each language instead of looking for strings to translate. This process is detailed in our documentation on Creating Multilingual Sliders with Revolution Slider and WPML. We have set the slider's language to Polish for the client, and they can now duplicate it and manually change it to English.
If this solution doesn't look relevant to your issue, please open a new support ticket.
