 <button *ngIf="pos.name == uname" type="button" class="btn btn-default       btn-sm delete" (click)="DeleteBulletin();">
   <span class="glyphicon glyphicon-trash glyph"></span>  Delete

Boostrap 4 does not support Glyphicons anymore, you can use Font Awesome instead:

npm install --save fortawesome/fontawesome-free

OR install the official Angular Fontawesome Package: https://github.com/FortAwesome/angular-fontawesome

and add the css File to your .angular-cli.json

"apps": [
          {
             ....
             "styles": [
                "styles.css",
                "../node_modules/bootstrap/dist/css/bootstrap.css",
                "../node_modules/font-awesome/css/font-awesome.css"
             ],
             ...
         }
       ]

],

Replace CSS class with the Font Awesome classes:

<i class="navbar-toggler-icon fa fa-bars"> </i>

recompile app: ng serve
