I responded to your email and showed you where to apply the strings so you can translate them.
Once you apply them like I showed you, you will be able to translate them in Strings Translation.
Please keep in mind that WPML can be a complex plugin to deal with and we are not the developers of WPML.
We offer support for our themes but we cannot offer support for 3rd party plugins.
I hope you understand, and you should be good to go now.
Have a good day 🙂
