Bookmarks - Data, Display, Current Page - Not Working how I thought it should

Hi,

I have the Pbix file (Bookmarks Example) in the below one drive link:

https://1drv.ms/u/s!Aknl2UdxdHn0eV7vhIK3lCyyEFc?e=UW6o85 

Within the pbix file I have the below four pages..

• AreaA  
• AreaB (Hidden)
• AreaC (Hidden)

Each page consists of the following...

• Three Calendar Slicers - Which shows Day, Month, Year
• Two Buttons- Which have actions to Bookmarks
• One Dropdown Slicer and Button - Which is used to Navigate to other Pages on the report
• Two Matix Charts - One Chart has one Row and one Value                                

                                        One Chart has one Row and two Values

My bookmarks are not working based on how I want it to work, so the two buttons Show More and Show Less I want the following to happen when you Click On..

Show More

• The Show More button will hide and Show Less button will appear
• The Matrix Chart below that has the Values AvailDayFlag and ExtraDayFlag will show 

          and the Matrix Chart that only has the one Value AvailDayFlag to Hide.

When the following button is Clicked

Show Less

• The Show Less button will hide and Show More button will appear
• The Matrix Chart below that has the one Value AvailDayFlag will show 
   

and the Matrix Chart that has the two Values AvailDayFlag and ExtraDayFlag will Hide.

I want any filters that have been applied to be kept when either clicking on the Buttons (Show Less or Show More) or when the below Slicer Dropdown is used which switches amongst different pages of the report.

But for some reason the Two Buttons  are not activiating when I am on different pages? Do I have to create a Bookmark per page for the Buttons? Or do I have to do something with the Bookmark Types as per below, as I have tried removing some but not working..

Thanks
