Hi, i have see that you have add the option for multilingual tour at the publish.
After the settings, what language will the components show depends on what language system your computer is installed. For example, if you input words in france volume of multilingual tour panel, the words will be shown on a computer with France language, but it won't show on a English-based machine.
However, you can also have a check as below. Please add a button in a sample tour and name it with different letters in English volume of the panel. You will find the button will show what you input in English volume on an English-based machine.
