Meeting Registration - Custom Question issues

I work for a family support, non-profit organization that needs to collect demographic data like race and ethnicity for our federal funders. As part of our federal grant deliverables, we provide trainings to parents. I have been asking these (not required) race/ethnicity questions to those who register for our Zoom meetings for many years and suddenly, these questions have disappeared from my meeting template. I also see that when I try to add a custom question I can only have a "one choice" or "text box" option for the answer. I can no longer provide multiple choice answers for registrants to select from.  I don't know why has this changed? Are there others out there who need to collect this kind of data.?
