Autopurge for VDI not working?

SEP 12.1 RU2

I've set autopurge for disconnected VDI at 2 days but it does not work...

I see clients last time online 10 days ago (in the properties section I see them as VMware).
If I set the filter in order NOT to see offline non-persistent VDI, I still see them... it's like SEP does not recognize them as non persistent VDI.

I've already performed all the steps described in best practices (vietool, clientprep and so on).
