Time Range double click error

Dear Daypilot-Support,

I am a developer for RTM Systems. I tried to double click an empty scheduler field as such (JavaScript React):

And encountered following error.

When I set allowMultiRange={false} in the DayPilotScheduler properties, the error disappears and the double click performs as expected.

Thank you for your help.

Kind regards,

Timo Klingler
