Right sidemenu and second button in navbar

I have a sidemenu on the right and want to place a second button. I tried the following code:

<ion-navbar primary *navbar>
    <button menuToggle>
        <ion-icon name="menu"></ion-icon>
    <ion-buttons end>
        <button (click)="selectTopic()">
            <ion-icon name="list"></ion-icon>
        <button menuToggle="rightMenu" *ngIf="isAndroid">
            <ion-icon name="more"></ion-icon>
        <button (click)="showModal()" *ngIf="!isAndroid">
            <ion-icon name="add"></ion-icon>

The problem is, that the second button (name=“list”) and the the button for menuToggle (name=“more”) are shown on android devices above each other and not next to each other.

Can you help me?

.bar-button-menutoggle {
display: inline;

Thank you very much! This solved my issue.
