Printing an 365Group calendar in Outlook web app is duplicating entries

Hi community,

I'm trying to print an 365Group calendar using the Outlook web app in Chrome (https://outlook.office365.com/calendar/view/month). 

Un-selecting my personal calendar first and selecting the proper 365Group.

Clicking on Print the preview window opens, but all calendar entries show up 3 times. 

Does anyone experience the same issue or knows what I'm doing wrong here?

The problem is just related to 365Group calendars and it looks like, if I print my personal calendar first(!) and an 365Group calendar afterwards the problem disappears.

Any feedback welcome!

Many thanks
