Conflict with Flatsome

Hi,

i have problem with Event Calendar and Flatsome theme. Elements aren’t clickable and console showing:

Uncaught TypeError: this.options.theme.replace is not a function
    at new n (flatsome.js?ver=3.12.0:69)
    at HTMLAnchorElement.<anonymous> (flatsome.js?ver=3.12.0:69)

    at Object.obj.initTooltips (tooltip.js?ver=5.1.4:260)
    at HTMLDivElement.obj.init (tooltip.js?ver=5.1.4:326)
