What gameplay feature is this bug affecting?
Title of Bookmarks

What's the issue? Please include any error messages you receive and as much detail as possible.
I use bookmarks to keep track of studs. However, sometimes when I add a new stud and name the bookmark, it will change a different bookmark to the same name. When I change the bookmark back to its original name, it sometimes changes a different bookmark to the same name. I do not know if it is a bug or if it is just my account that is doing it

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
It came happen to any of my bookmarks. Even ones that are not studs.

Any screenshots you can provide us with?
Screenshot won’t be of much help seeing as it’s just 2 bookmarks with the same name but to different links

Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
1. I bookmarked a new stud.
2. I already have 5 different studs bookmarked
3. I title the new bookmark and press update
4. The new bookmark and one of the old bookmarks have the same name
5. They go to 2 different links. The link the the correct stud with the correct title and the correct stud with the wrong title.
Ex: I have a stud named Salem and a different stud named Bear. I bookmark a new stud and title the bookmark Loki. All of a sudden, the bookmark for Bear gets titled Loki as well. However, the bookmark that was originally for Bear but the title was overwritten still goes to Bear and the bookmark originally for Loki goes to Loki.
