10. The change reason field appears incorrectly in the model management page and should not be displayed, affecting interface cleanliness and operational smoothness.
11. State transitions in the configuration may cause display anomalies in symbols, affecting real-time data visualization.
12. Once historical events generated by a real-time analysis are manually deleted, the same analysis instance cannot regenerate them.
13. AI chat now searches user-uploaded documents for non-TDengine topics.
14. After opening a configuration dashboard from the configuration list in the dashboard main menu, clicking edit triggers an error indicating that the corresponding element cannot be found.
15. Multiple attribute fields cannot be edited individually; all modifications must be made via the attribute template.
16. KPI attribute save operation failed.
17. The Y-axis settings in the Analysis Workbench fail to apply, affecting chart data display.
18. When viewing the child element panel of an intermediate element in the element browser, a system error is triggered and the panel fails to load.
19. Clicking any filter item in the element filter and then clicking the top‑left logo triggers a system error, causing abnormal page behavior.
20. The offline documentation page experiences abnormal style rendering when opened, affecting the normal viewing of document content.
21. After canceling the limit conditions of an attribute template, attempting to set them again triggers a system error.
