Navigation error in calendar? link does not work

Hi Support team,
I think I have found a similar bug to the one mentioned for the weekly calendar in this post: https://premium.wpmudev.org/forums/topic/weekly-calendar-date-header-not-coorect

With activated navigation in the calendar view the link to the next month does not work, if I try to click on it. What is a little bit strange-when I open the same link as a new tab, the next month is showing.
Does anyone else has this behaviour,too. Is there a solution?
Many thanks.
Jörgen
