Events won’t show in Internet Explorer

Hello

Thank you for this plugin that helps a lot.
On my website it works fine on all browsers, except with Internet Explorer.
I used the short code.
See on this page : https://etiennechampollion.com/concerts/

Is this an issue, or can you help me ?

Thank you again,

Jouski
