files tagged with " do not show up in Database e.g. (7")

I just figured that my files tagged as

(7")

do not show up in Moode Audio Database.

When I rename to

(single)

they do show up.

I can live with it. Just wanted to mention. Maybe there is a easy solution.

small addition. 
Just figured out that the tracks do show up in Album and Tag view. Only in Folder view I do not see them at all.
Nevertheless, even though I see them I can not play them. Just nothing is happening.
After editing the tag and folder path ("single" instead of "7"") all is working fine

I'd suggest you do not include neither single, nor double quotes in the file / folder names (as well as brackets, punctuation and any special symbol, like % or & and thee like, as they can interfere with search syntax / criteria, or worst misbehave among different file systems).
The tags can contain those characters, though, without any trouble resulting.
