How to set back to queued delta mode in LO Cockpit?

Hi,

I encountered a problem while trying to set the update mode of the extract structures from Unserialized V3 Update to Queued Delta.

It prompts me saying that there are still entries in the queue. I went to check but there was nothing. I think I have to stop the V3 Update before I can set it to queued delta mode, correct? How to do it?

Please help.

Thanks,

Shunhui.
