Jira Cloud Board – "Create" button disappears after modifying board filter JQL

[씨엘]

Details

We are using a Jira Cloud Scrum board called QA Board within a single space (Web_Dev). Within this space, we operate two boards by design:

• QA Board → handles Bug issues only
• Work Board → handles all other issue types (Story, Task, Epic, Subtask)

The QA Board is filtered to show only Bug-type issues. The original board filter JQL was:

project in (10099) AND issuetype in (10077) ORDER BY Rank ASC

(10077 corresponds to the Bug issue type)

We attempted to modify the JQL so that the inline "+ Create" option on the board would allow creating Bug issues (currently it defaults to Task only). After editing and saving the JQL, an unexpected problem occurred.

Expected behavior

• After saving an updated board filter JQL, the "+ Create" button (both the global blue "+ Create" at the top of Jira and the inline "+" on the board's columns) should remain visible and functional.
• Reverting the JQL to the original query should fully restore the previous behavior.
• The available issue type dropdown for board inline creation should reflect the issue types allowed by the filter (e.g., Bug should appear when filter is issuetype = Bug).

Actual behavior

• After saving the modified JQL filter, the "+ Create" button completely disappeared from the board UI.
• Even after reverting the JQL filter back to the original value (project in (10099) AND issuetype in (10077) ORDER BY Rank ASC) and performing a hard refresh (Cmd+Shift+R), the Create button still does not reappear.
• The board still loads existing issues correctly, but there is no way to create new issues from the board.
• No error message is shown – the button is simply absent.

What I tried

1. Reverted JQL to the original query → no change
2. Hard refresh / browser cache clear → no change
3. Logged out and back in → no change
4. Verified Issue Type Scheme: all 5 issue types (Bug, Story, Epic, Task, Subtask) are configured for the project (WD: Scrum Issue Type Scheme)
5. Verified user permissions: I am the filter owner with editor rights
6. Tried in a different browser → same issue
7. Checked board sub-filter / swimlanes / columns → no apparent misconfiguration

Additional context

• Jira Cloud (new UI / space-based)
• Project type: Software project / Scrum
• Issue Type Scheme: WD: Scrum Issue Type Scheme (Default: Bug)
• Board filter is shared by 2 boards ("QA Board 2개에 대한 필터")
• Workflow: custom (시작 → QA TESTING → TO-DO → IN PROGRESS → IN REVIEW → QA READY → CLOSED, with REOPENED branch)
• Columns on board: QA TESTING / 해야 할 일 / 진행 중 / QA READY / 완료

Why this matters

Our QA team relies on this board to triage and create Bug issues during testing. Without the "+ Create" button, QA testers cannot register bugs directly from the board, which significantly slows down our QA cycle and forces us to rely on manual fallback (top-level "+ Create" button), which is less efficient and breaks the team's established workflow.

Any guidance on:

1. What could cause the Create button to disappear after a JQL edit, and
2. How to restore it without recreating the board from scratch

would be greatly appreciated.

Thank you in advance!
