how can i remove multiple bookmarks from button

Hi , randomUser21 

According to your description, you want to just show some of the bookmarks in it .

For your need , you can try to create the Bookmark Group:
When editing a report, you can create and use bookmark groups. A bookmark group is a collection of bookmarks that you specify, which can be shown and organized as a group. You can't create groups of personal bookmarks.

For how to create a BookMark Group , you can refer to :
Create report bookmarks in Power BI to share insights and build stories - Power BI | Microsoft Learn

Then you can configure the Bookmark group in your bookmark navigation .By default, All Bookmarks will be shown in the Bookmark navigator. However, you can create and select a specific Bookmark group to only show the Bookmarks within that group.

For this , you can also refer to :
Power BI Blog: New Page and Bookmark Navigators < Blog | SumProduct are experts in Excel Training: Financial Modelling, Strategic Data Modelling, Model Auditing, Planning & Strategy, Training Courses, Tips & Online Knowledgebase

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,

Aniya Zhang
