Multi-day events in Zoho Backstage

Multi-day events in Zoho Backstage

I'm trying to setup a multi-day event in Zoho Backstage but when selecting an end date, the system only allows me to select the same end date as my start date (e.g. if my event starts on the 12th of March, I'm forced to also select 12th of March as my end date).

Is there a reason for this?
