Mobile survey preview showing different information

Dear all,

I have created a short JavaScript code that randomises some parts of the text shown to my respondents in a specific question. The randomization works fine but I am just struggling to understand why the mobile survey preview shows different information compared to the computer survey preview for the same question during a test. I always thought that the mobile version is supposed to present the exact same information/text as the computer version but just in a different format/view. I am attaching a screenshot to help visualise the issue. What am I missing? Thanks a lot in advance for your help.
