Ahh, then you need to redeclare the parameters of this CSS class:

div.bx-tl-item-text div.bx-tl-content {

    position: relative;

    max-height: 250px;

    text-overflow: ellipsis;

    overflow: hidden;

}

Go to Studio->[Your template name]->Styles->Custom Syles area and add there smth like:

div.bx-tl-item-text div.bx-tl-content {

    max-height: 200px;

}
