Hi, Lauren. Sorry you’re experiencing this.
1)
You might try playing with this setting: wp-admin > Events > Settings > Display tab > “Events template” option — to see if changing it makes things work better for you — maybe being more integrated with your theme?
Please let me know how this goes for you.
2)
Also, for your second issue of No Events Found notice, do you actually have events occurring in April?
If you think it would help after today (April 30), please also provide a link to your Events page so I can see the issue.
