Also, the “view in my time” is too high.
Please add this CSS code to EventON > Styles (If you don’t see any change, EventON > Scripts & Styling > turn off Write styles to header > save settings > turn on Write styles to header):
.eventon_list_event .evcal_desc em.evo_mytime { margin-top: 6px !important; }

Hello,
Please check for latest version of this software from here Your issue might be related to an older version you are running and we might have resolved this already in the newer version update. If you are on latest version of our software and the issue still persist please let us know.
To update eventon addons: You can download latest eventon addons from myeventon > my account. Then you can go to your website, deactivate old addon and install new one and activate then delete the old addon. This link will further explain the process. Also you can follow us on twitter to get real-time announcements on updates!
I don’t think that Physical tag was ever visible, since every event is physical by default.
Hello,
As a temporary solution please go to EventON > EventTop > EventTop Main Day block fields > enable Event Day Name or any other you like.
