Welcome back,
Thank you for sending over your System Information. We are pretty limited on theme conflicts even though the theme author has integrated styles/templates for our plugins. Have you tried contacting them and searching their forums to see if any users have experienced the same issue? I did a search of our forum threads but can’t find any threads resembling what you’re experiencing.
I might be off here, but have you tried visiting Events > Settings > Display and selected different options found there? Let me know if you’re able to find anything out from your theme author and if trying different options under the ‘Display’ tab makes a different.
Have a great afternoon. Cheers!
