Bug in parsing folders with multiple sets of brackets

Linux, running 4.6 (QNAP package)
I have some folders:
drwxrwxrwx 2 ssods ssods 4096 Dec 26 15:50 Blu & Exile - Below The Heavens (2007) [V0]/
drwxrwxrwx 2 ssods ssods 4096 Mar 19 21:32 Blu & Exile – Give Me My Flowers While I Can Smell Them [2011] [320 kbps]/
drwxrwxrwx 2 ssods ssods 4096 Apr 26 14:52 Blu & Sene - A Day Late & A Dollar Short [V0]/
The middle one will not import. Subsonic doesn't even see it. I suspect it's because of 2 sets of brackets.
I copied them into a new folder:
[admin@qnap music]# cp -rv Blu*Flowers* Blu_Exile-Give_Me_My_Flowers_While_I_Can_Smell_Them
`Blu & Exile – Give Me My Flowers While I Can Smell Them [2011] [320 kbps]' -> `Blu_Exile-Give_Me_My_Flowers_While_I_Can_Smell_Them'
And subsonic saw them fine now, so wasn't a permission issue.
I have many folders with multiple sets of brackets in the folder name that don't display. This is just 1 example.
