Event minutes time not manually adjustable on the Mac

I cannot create an event that starts at 11:20. Dropdown field just allows 15 minute intervals. Editing the time fields seems impossible. But the Calendar detail setting is 5 minutes.
Am I missing something?

eMClient 10.2.1712 on macOS.

Answering to myself.
This seems to be a bug in the macOS version.
eMClient in Win 11 does allow me to enter any time for an event by editing the time field.

Yes i can also confirm that you cannot click in the event “minutes field” and change it on the Mac V10.2.1712, but "you can in Windows V10.2.1712 as per the screenshot example below.
