Hi Duy,
Try creating a new Template for the DataCollector Frame rather than using the default framework, may be it should work for your issue.
Also check if you have implementer latest collection/correction notes:
SAP Notes for DBA Cockpit for all four versions mentioned before:
1558958 | SYB: DBA Cockpit Correction Collection SAP Basis 7.02 / 7.30 |
| 1619967 | SYB: DBA Cockpit Correction Collection SAP Basis 7.31 |
| 1882376 | SYB: DBA Cockpit Correction Collection SAP Basis 7.40 |
