Based on the knowledge sources provided, it seems like you're experiencing an issue similar to the one discussed in this [Github issue](
https://github.com/airbytehq/airbyte/issues/23349). The issue is about non-breaking schema changes being detected as false positives. In this case, the notification for non-breaking schema changes stays up, however, when going through the schema change review process, no changes are detected. This issue was confirmed by several contributors and was eventually closed, indicating that a solution was found. The process to review detected non-breaking schema changes is outlined in the [Airbyte documentation](
https://docs.airbyte.com/using-airbyte/schema-change-management#review-detected-non-breaking-schema-changes). According to the documentation, you need to manually approve any detected schema changes for the schema in the destination to change. However, there are some observations and improvements suggested in this [Github issue](
https://github.com/airbytehq/airbyte/issues/26348) that might be relevant to your case. Some users have reported that after clicking on “review changes” and then clicking “OK” in the modal, they think the change has been applied, so they navigate to another screen and see the modal “discard changes”. If you're still experiencing the issue, it might be worth raising a new issue on the [Airbyte Github](
https://github.com/airbytehq/airbyte/issues) to get help from the community and the Airbyte team.
