An unwanted loading bar, that gets stuck, is showing up under my navbar on Android.

This is what my HTML looks like:

<ion-header>
  <ion-navbar>
    <button ion-button menuToggle>
          <ion-icon name="menu"></ion-icon>
        </button>
    <ion-title>History</ion-title>
    <ion-buttons end>
      <button ion-button icon-only *ngIf="history" (click)="clearHistoryAlert()">
        <ion-icon name="trash"></ion-icon>
      </button>
    </ion-buttons>
  </ion-navbar>
</ion-header>

<ion-content>
</ion-content>
