Project sidebar stuck showing unread tasks with no visible filter reset

What version of the Codex App are you using (From “About Codex” dialog)?

26.707.31428 (5059)

What subscription do you have?

Pro

What platform is your computer?

Darwin 25.5.0 arm64 arm

What issue are you seeing?

One project in the sidebar of the new ChatGPT Codex app only displays unread tasks. Tasks that I have already read—those without the blue unread indicator—are missing from that project’s list, although I can still find and open them using Search.

Other projects correctly display all unarchived tasks. I cannot find any filter control in the current UI, and I did not knowingly enable an unread-only filter.

Fully quitting and restarting the app does not resolve the issue.

What steps can reproduce the bug?

I do not know what originally caused the project to enter this state, so I cannot provide deterministic steps to reproduce it.

Once the state occurs, it can be observed as follows:

1. Open the ChatGPT Codex app.
2. Expand the affected project in the sidebar.
3. Observe that only tasks with the blue unread indicator are displayed.
4. Search for a known read, unarchived task belonging to the same project.
5. Observe that the task appears in Search and can be opened, but is absent from the project’s sidebar list.
6. Fully quit and reopen the app.
7. Observe that the unread-only behaviour persists.

The issue affects only one project; other projects display both read and unread unarchived tasks.

What is the expected behavior?

The project should display all unarchived tasks, or provide a visible way to clear an active filter.
