Adding speaker profiles to Webinar - up to 3 or up to 10?

I want to add more than 3 speaker's profile information to a webinar I'll be setting up soon with registration.

Looking at  https://support.zoom.us/hc/en-us/articles/115002548166-Customizing-webinar-branding-settings#h_2a845adc-937c-4488-8ac4-80af8d743d5b

This help file says:

"You can information for up to 10 speakers. If you already have 3 speakers listed, the Add another speaker link does not display."

The above sentence doesn't make sense, it currently suggests it's not possible to add more than 3 practically but starts off sounding like you can add up to 10?

Can someone clarify if I can add more than 3 speaker profiles or not?  Thanks!
