Statistics on Selected Documents don't work on version Beta 64bit

Here’s what it looks like when I try to run statistics on a selected number of chapters:

I get the above result only when there is no Binder selection. If a document is selected in the Binder the “Selected Documents” statistics show expected results.

Now that I selected the overall binder it works but I can’t help but find that’s a sort of bug since it used to work fine before this without binder selection - actually no, it doesn’t seem to work with the banner selection, it just gives me a constant number that’s not real

However many scenes I choose if the binder is picked, the amount of words in selected documents is also the same. Doesn’t seem to work.
