Mat Table Pagination Not Working When Data length is less than 9 - Angular

Question

Im using mat pagination, it works correctly when the length is greater or equals than 10, but it breaks when the length is less than that.

Version angular: 13

working correctly

broken

my last try:

TS:

@ViewChild(MatPaginator) paginator: MatPaginator;

this.paginator._intl.itemsPerPageLabel = 'Elementos por página';
this.paginator.length = res.length;
this.paginator.pageIndex = 0;
this.paginator.pageSize = 25;
this.dataSource.paginator = this.paginator;

The HTML: <mat-paginator [pageSizeOptions]="[5, 10, 25, 100]" showFirstLastButtons></mat-paginator>
