Bitbucket integration doesn't work for one of the projects.

Bitbucket integration doesn't work for one of the projects. 

We use cloud Jira. There are several projects (software). Some time ago development section (blanches, commits) have stopped displayed in the tickets one of the projects.

I checked issue layout, and Bitbucket integration several time. 

And no longer know what to do.  Help please.

Hi Alexey,

Welcome to Atlassian Community!
When integrating Jira with BitBucket or Github, for example, the development panel should appear automatically, it's not a field that we can add.
As per your screenshot, you are using a classic project. Is this issue happening when you see a ticket with the new view or the old view?
On the new view, some fields are hidden and we need to click on "Show more" on the right side.
On the old view, all fields show on the right side. If you search the ticket thought Issues and filters, you will see the option on the top to "See the old view", but if you are on the board, you can click on ... > Turn off for now to disable the Jira Labs, so all screens for Classic projects will show the old view.

Please, test on both view and let us know if the development panel appears.

Regards,
Angélica
