In using JIRA i have three different projects to serve as what is called a pre-development board. This is where the stories get requirements, grooming, etc to get ready for a developer to take on. Then these stories are transferred from this project to a development board. I have a column in the pre-development board called "ready", it serves a done column. This is where stories move when they are ready for the development board.
I move the stories using a bulk action. But some of the stories disappear when i transfer them. You can find them if you look specifically for them by typing in the URL, but the stories are not to be found in the backlog or the board.
I'm trying to understand why this happens.
