Based on my observations in this forum, I would not expect a Time.ly answer to this…
Alison, have a look at The Events Calendar PRO. I am using it on anaf284.ca and I have found their support to be excellent!
I am using All-in-One Event Calendar by Time.ly at legion8whiterock.ca and updated the plugin to v2.6.0 and then WordPress to v5.3 with no issues.
Just a shot in the dark but is your site using a hide title plugin?
