CSS- Sticky Header content overlaps onScroll

Question

In Angular application I am making Filters and Header row element sticky. I am using HostListener and windowscroll to achieve this functionality. The problem I am facing is Header and filter content is overlapped with the results when user scroll down.

I need help to fix this overlap.

        </div>

    </div>

    <div class="filters-data-result">
        <app-filters-data-result *ngFor="let item of filters; let i = index" [item]="item" (onRemoved)="remove(item)">
        </app-filters-data-result>
    </div>
</div>

.css

    
.mat-elevation-z5 {
  position: relative;
}

.sticky {
  position: fixed;
  top: 100px;
}

div.filters-data {
    display: flex;
    flex-direction: row;
    flex-wrap: nowrap;
    justify-content: space-around;
    align-items: center;
    align-content: flex-start;
    padding: 20px 0;


    .im-results {
        display: flex;
        flex-direction: row;
        flex-wrap: nowrap;
        justify-content: center;
        align-items: center;
        align-content: center;
