Aligning buttons in a list

I’m displaying a list of buttons however they don’t align properly:


As you can see (especially when looking at the divider lines) there is some sort of padding on the left side.

My code for displaying this list:

    <button ion-item *ngFor="let entry of entries" (click)="goToEntryDetailsPage($event, entry.group_id)">
      <!--{{entry.group_id}} {{entry.sub_id}} -->

Can someone help me?
