Buttons changed their bookmarks???

Hey Everyone,

So just wanted to ask if anyone ever had anything similar happen and if there are any solutions to this (Want to prevent this from happening ever again)

Long story short, I have created a report for a customer which cointains multiple bookmarks. Essentially I`m using them to create a navigation menu. When i saved the report yesterday everything was fine, today I woke up to something weird that is half of my buttons have changed their associated bookmarks. So instead of moving +1 page it now moves +2 pages.

any ideas?

Thanks in advance!
