Nested Tag view bug ?

[Gilles B. 2]

Hello,
In the windows 10 beta version, it's impossible to see notes in the parent tag.
I can see them only in the last "child" tag.
Exemple : 
If i have a tag named "books" and two tags under it named "book_one" and "book_two", clicking on the tag "books" return nothing.
Even if i place the tag "books" and "book_one" on the same note, clicking on the tags "books" return nothing.
Sometimes i can the see the notes for 1 sec, but the view disapear and i just have the message no notes found. 
Other times i see a little message in red : "no search longer than 1023 characters"
