I started with Jira 5 and have subsequently upgraded over the years to Jira 8. Originally newly created issues were create fine in terms of a project/issue key (ISSUE-1, ISSUE-2, ISSUE3 etc etc). Somewhere along the line these sequential numbering has gone a miss, newly created issues now are in the hundreds of thousands (ISSUE-240104, ISSUE-240105 etc), Jira works as expected but some how and I have no idea how 240,000 has been added to my numbering sequence. It would be nice if I could some how subtract this 240,000 and the system generate the next issue number with somthing that is a little easier to convey in spoken conversation!
Thanks
