Meeting invite visible before sending

My System time was 3:55 PM IST and i was scheduling meeting for 4 PM IST with my teammates. And i forgot to send that meeting, but suddenly i received email saying my team member joined the meeting at 4 PM IST which is still in draft. (I didn't send).

when i checked his Zoom meetings and found my draft meeting was showing in his Zoom meetings and he is getting Zoom Pop-up for joining the meeting.

Is this Bug ?

Zoom Version : 5.15.7 (20303)

Windows OS : Microsoft Windows 10 Enterprise (Version 10.0.19044 Build 19044)
