We advised the Developers/Site Owners not to edit the Theme Styling Directly because your customization may be overwritten during next Theme Version Update. We advised to implement any styling within Theme Options. There is a option named Custom Code within Head Area. This customization will not be affected during any Theme Version Updating.
For your quote issue please paste the following code in the Custom Code within Head Area of your Theme Option.
Code:
<style>
blockquote:after, blockquote:before { content: none; }
</style>
