Desk Field Not Showing in Analytics

Desk Field Not Showing in Analytics

Hi there,  
I recently added a field to our Zoho Desk Ticket Information. I went and added the data retrospectively to the tickets. It is also marked as required, so all new tickets cannot be closed off without it being filled in. When I try to run a report in Zoho Analytics, the data is not there. There isn't even a column for it. I can't create a report for it or set it as a filter. It just doesn't exist. What is strange is that when I use the Analytics in Zoho Desk, I am able to pull the data and download it via CSV.

The field is "Involves Engineering". Have attached images below.


Has anyone experienced something similar???

Kind Regards,
Matt
