Hello

I have two members tables on my website.  Both source their data from the same SQL view, but the presentation differs slightly (different user needs). 

In the first table, when viewed on mobile, the phone number is clickable to call.  It is a string and no transform value has been done. 

In the second table, when viewed on mobile, the same phone number is not clickable to call.  It is a string and no transform value has been done. Since the data is from the same SQL view, and the column settings are the same, I am struggling to work out why the first can click to call, but not the second table. 

I did try to use transform value following these instructions for phone, but then the table just got into a 'grey spinning loop' and displayed no data.

This is not an urgent query, as the table does work, it's just that you can't click to call on mobile which kind of defeats the purpose.
