when i am configuring columns in board setting, there are way too many unmapped statuses in the "column management". like almost 100 statuses and many of those are duplicated. For example, I have "15 unmapped statuses of "In Progress" and with "o issues" in the statuses. It does not happen in other boards under the same project.
When Jira cannot work out a simple list of status that a board might need to see in its columns, it defaults to just adding all the available ones. This can happen when you've got complex filters that select for many workflows.
This is what you are seeing - your board filter does not define a project, so Jira has no choice but to list all possible status for inclusion. Because any issue on the board could be using any of the workflows you have.
