Job title - internal alerts

Hello :)

I have set up a few forms with internal alerts that have all worked fine, except for this one needs to have job title included in the alert. I have tried all of these: job_title {{ person.job_title }} or {{ person|lookup:"job_title" }}.

None of them work, the final one puts in “None”, but the form field “Job Title” is mandatory and is lined up with the already set property “ job title”. I can’t work out where I am going wrong, as if you visit the profile of the form submitter, their job title is clearly there. 

Anyone else had anything like this and can advise?

Thanks!
