Hello,

1. This issue seems to be caused by WPML plugin since it doesn’t load translations for AJAX requests. Are you able to contact plugin’s support and ask this question? Back to us if it should be fixed from our side.

2. Add the following code snippet to the Custom CSS for desktop devices only

.filters-inner-area .filter-widget {
    width:20%;
}
.filters-inner-area>div:nth-of-type(5n+1) {
    clear: both;
}
.filters-inner-area>div:nth-of-type(4n+1) {
    clear: none;
}

3. As we can see, there is no integration guide with Basel theme in plugin’s documentation. This instruction is related to some other theme, but not ours. You can try to contact plugin’s developers also for the instruction for our theme integration too. Write us if you will need help implementing their fix in our theme.

Regards
