List's bottom border disappear

Hi all
the bottom border of list in my Ionic 2 project doesn’t show, I’m not sure if this cause from transpile, since I update to RC3 and get error copy message.


html code:


    <button ion-item (click)="navToTRA()">
      <ion-icon name="md-train" item-left></ion-icon>TRA
    <button ion-item (click)="navToBus()">
      <ion-icon name="md-bus" item-left></ion-icon>Bus
    <button ion-item (click)="navToAbout()">
      <ion-icon name="md-clipboard" item-left></ion-icon>About

and the error message

my ionic info
