My carousel worked fine till last week, but now the animations gone.

I have two carousels. one with fade animation and one with slide, and now they both change slides in instant, without animations

here is my code:

<mdb-carousel [controls]="true" [indicators]="true" [animation]="'fade'"  [interval]="5000">
  <mdb-carousel-item *ngFor="let item of data.carousel_items">
    <img
      [src]="baseUrl + item.content.image.url"
      class="d-block w-100"
      alt="..."
    />
    <div class="carousel-caption">
      <h3>{{item.content.title}}</h3>
      <p class="main-text">{{item.content.mainText}}</p>
      <p class="other-text">{{item.content.otherText}}</p>
      <button *ngIf="item.content.hasButton" class="handes-btn light-white wide">
        <a [href]="item.content.buttonLink.url">{{item.content.buttonLink.name}}</a> 
      </button>
    </div>
</mdb-carousel-item>

I did not updat angular or MDB package versions.
