Sometime when I already have added a hardware to recording server,I still can change the param in other way but not in the Setting’s tab.When I doing that, the param between device and the Setting tab are not the same.

I have tried refresh the recoding server in management client and the UpdateSettings Method of ISettingsManager in the driver,but It seems doesn’t work. The param displayed in the Setting’s tab still doesn’t Update.

This might be a known issue. There is a hotfix for 2019R3 Recording Server and a permanent fix in 2020R1 and newer.
