Incorrect booktype reported

I noticed something strange after burning a DVD+R DL media with ND3550. The booktype is reported as DVD-ROM if the disc is in the ND3550, but it is reported as DVD+R if it is inserted in another (different brand) drive. Booktype for DVD+R DL was already set to DVDROM before burning and I made no changes. I am using Liggy’s Bitsetting Firmware 1.07. Is this normal?

Some drives report the Booktype wrong, some even are confusing disctype & booktype.

What drive is the other one?

 I have also seen incorrect readings especially in external drives
