Custom Scan - Multi Value tags

Hi,

i had the impression that if i enter the tags into custom scan config "TAGS TO SCAN", then the TAGS gets seperated.
This doesn't seems to be the case

I have TAGS like MOOD which contain: "beautiful, sad" and after scanning with custom scan they aren't separated into single TAGS, so they show up in Custom browse as "beautiful, sad"

Am i on the wrong track here or do i have to configure something else to separate the TAHS?

The MOOD TAG is explicitly NOT entered into the SINGLE VALUE field of custom scan config.
