Search not displaying all stories with the searched "keyword"

Currently, we have experienced that the search in the project is not displaying all stories with that keyword. (projectID: 6e62ee)

First search, I was able to search 22 stories with this keyword, but when I opened the Labels column, I opened stories with the label “braze” then 3 new stories appeared in that list.

It´s crucial for us to see all to stories when we are searching for that specific keyword.
