Thank you for your bug report. Can you trigger the issue by creating an event manually or is that, step 1 and the rest of description seem to somewhat disagree.
It would be nice to also report upstream on https://gitlab.gnome.org/GNOME/gnome-calendar/-/issues , or at least check existing issues there since there are some problems already reported around ICS and timezone, example https://gitlab.gnome.org/GNOME/gnome-calendar/-/issues/586 ** Bug watch added: gitlab.gnome.org/GNOME/gnome-calendar/-/issues #586 https://gitlab.gnome.org/GNOME/gnome-calendar/-/issues/586 ** Changed in: gnome-calendar (Ubuntu) Importance: Undecided => Low ** Changed in: gnome-calendar (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1906059 Title: Gnome calendar mishandles timezone during moving across calendars To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-calendar/+bug/1906059/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
