Issues Filtering Events with Multiple Categories

Hello, on my website I have a page to display events in grid form with a category filter. I noticed events with multiple categories have trouble showing when filtered.

For example, Event A has categories Cat Z and X. When using the filter, I can find Event A under Cat Z, but not under Cat X.

Upon inspection, I see event categories are added to the event’s <div class="mep_event_grid_item"> as a class name prepended with mage-. This seem to only occur to one of the categories, not multiple. For example, Event A has the CSS class names mage-cat_z and cat_x, NOT mage-cat_x.

Is the plugin capable of assigning and filtering events with multiple categories? Please let me know if this can be achieved or fixed. Thank you!
