Buttons won’t right align…

1. So, when I left align or center align a button, it works.

However, when I right align a button and update, the page has the button left aligned. Please help. My html reads:

<div class=”wp-block-button alignright has-custom-width wp-block-button__width-25″>Plan Your Visit Today</div>

2. As an aside, sometimes when I save or update and come back to edit, the page shows multiple buttons have randomly been added to my page…thoughts on this also appreciated.
