Amibroker Study Label disappearing after restart

Hi,

I have added a label on the chart on symbol OKLO. Copied the same label from symbol OKLO and posted on another symbol CEG. Saved the database.

Once I restart Amibroker, label disappears on CEG.

Tried to recreate the scenario in the below youtube video.

I have been doing something wrong and not able to figure out what it is.

Can any expert explain what am I doing wrong?

Thanks in advance.
