Some items with the MSSQL by ODBC template assigned to a host being monitored via proxy are showing a status "Not supported", even though data is being collected correctly.

Execute now or Test does not fix the item state from Not supported to normal.

I have noticed that temporarily switching these items to "Keep history", refreshing the cache, and using Execute now causes the status to return to "normal". After disabling "Keep history", the item's status remains "Enabled" and continues to function correctly until a potential issue occurs.

Steps to reproduce:

1. Create a host with MSSQL by ODBC template
2. Verify everything is monitored correctly
3. Arrange a problem (stop monitored MSSQL server or make network issue)
4. Wait until item gets status Not supported
5. Fix the problem from 3.
6. Check the Latest data

Result:

Items without keeping history (Get last backup, Get performance counters,...) stays in Not supported state, but dependent items are collecting data normally.

Expected:
Get job status was manually corrected via workaround above

Get last backup and Get performance counters are in bad state

If you require any further details or logs, please let me know, and I will be happy to provide them.
