Displaying CDRW for DVD+R disc and it's not finalized.

I wrote a backup with CB latest and it’s displaying CDRW for the DVD+R disc (read only, the little rw sign stands for the +). When i checked the disc windows couldn’t read it, cause it’s not finalized (i can see the contents from nero burning room).

I’ve opened/closed the dvd-rom.

LG DVD writer: HL-DT-ST DVDRAM GSA-4163B.
Used disk type: Verbatim, double-layer DVD+R 8.5GB, 2.4x, certified up to 240min

PS: i know Panic is happy about the rw features but i wouldn’t mined seeing the contents of my disk :).
