Hello @Kyle Jones
What steps did you go through to change the name of your board?
What do you mean the tickets are "missing"? Are you able to display the board but no issue show? Or are you not able to display the board at all? Do you get any error messages?
The issues shown on a board are determined by the Filter Query associated with that board. If you did not change the Filter Query, and if the Filter Query has not been deleted, and if you have permission to view the saved filter, then issues should still display in the board if there are issues that match the query criteria.
