Side menu is showing up in every page after the device width is greater than 990px

I am using ionic4/angular4. I have created a side drawer menu .so all the menu HTML is in app.component.html and I accessing it in only one page but don’t know why the menu is showing in every page when device width is greater than 990px
app.component.html

<ion-app>
  <ion-split-pane>
    <ion-menu side="end" size=small>
      <ion-header>
        <ion-toolbar color=primary>
          <ion-title style="font-size:15px;font-family:  DINPro-Bold;color:#FFBF00">
            Menu
          </ion-title>
        </ion-toolbar>
      </ion-header>
      <ion-content>
        <ion-list style="font-size:5px">
          <ion-menu-toggle auto-hide="false">
            <ion-item lines="none" routerLink="/profileedit">
              <ion-img src="../../assets/main_profile/edit.svg" slot="start"></ion-img>
              <ion-label style="font-family:  DINPro-Bold;font-size:12px">Edit Account</ion-label>
            </ion-item>
          </ion-menu-toggle>
          <ion-menu-toggle auto-hide="false">
            <ion-item lines="none" routerLink="/profile">
              <ion-img src="../../assets/main_profile/tnc.svg" slot="start"></ion-img>
              <ion-label style="font-family:  DINPro-Bold;font-size:12px">T&C</ion-label>
            </ion-item>
          </ion-menu-toggle>
          <ion-menu-toggle auto-hide="false">
            <ion-item lines="none" routerLink="/privacy">
              <ion-img src="../../assets/main_profile/policy.svg" slot="start"></ion-img>
              <ion-label style="font-family:  DINPro-Bold;font-size:12px">Privacy Policy</ion-label>
            </ion-item>
          </ion-menu-toggle>
        </ion-list>
      </ion-content>
