I have a child UDT and clicked the General Scan Class override by mistake. Now I want to "un-override" it but when clicking Apply or OK, this doesn't seem to save the setting. Is anyone else seeing this?

Similar problem:

> Hello, Since 7.7.2, I can not override the alarming section of a UDT-instance. Clicking on “Apply” or “OK” does not save the overridding anymore. I tried the same operation on a 7.7.1 and it does work. Operations: [ol] [li]Create a UDT[/li] [li]Create a tag in UDT[/li] [li]Create an alarm on this tag[/li] [li]Instanciate the UDT[/li] [li]Double click an add a new alarm or override the existing one[/li] [li]Click on “Apply” or “OK”[/li] [li]Check that changes have not been saved.[/li][…

Thank you,
