Good morning,

Look like there are few css conflicts between your theme and our plugin. This is something normal and easy to fix.

Please open the plugin Fonts & Colors go to Custom Style tab and paste this code:

body .stec-layout-month-daylabel p { margin-bottom: 0 !important; }
body .stec-layout-month-daycell .stec-layout-month-daycell-wrap .stec-layout-month-daycell-num { line-height: 1.7 !important; }
body .stec-layout-event-preview-left-text-title { font-family: Roboto; margin-bottom: 0 !important; }
body .stec-layout-event-preview-left-text-sub { margin-bottom: 0 !important; }
body .stec-layout-event-preview-left-text-date { margin-bottom: 0 !important; }
body .stec-layout-event-inner-top-tabs p { margin-bottom: 0 !important; }
.stec-layout-agenda .stec-layout-agenda-events-all-load-more p {    line-height: 1.2 !important; margin-bottom: 0 !important; }
.stec-layout-event-inner-button-style p { margin-bottom: 0 !important; }
body .stec-layout-week-daylabel p { margin-bottom: 0 !important; }
.td-footer-wrapper { overflow: hidden !important; }
body .stec-layout-month-daycell-events .stec-layout-month-daycell-event .stec-layout-month-daycell-event-name { line-height: 2.3 !important; }
body .stec-layout-week-daycell .stec-layout-week-daycell-wrap .stec-layout-week-daycell-num { line-height: 1.7 !important; }
body .stec-layout-week-daycell-events .stec-layout-week-daycell-event .stec-layout-week-daycell-event-name { line-height: 2.3 !important; }

Save the settings and let me know if everything is okay.
