I have ##COM_MATUKIO_FIELDS_TITLE## set to show per seat in the default booking form. However, only the first seat drop-down works. Every other seat drop down is frozen. If the field is set to "required,' registration is blocked since the additional drop-downs don't work. This behavior exhibits on desktop chrome, IE, and Firefox.
Oddly, it works fine with Android chrome on a mobile phone.
This was reported to me by a customer, and then I replicated it myself on my Windows laptop. I have to disable this until it is fixed.
