MusicBee not importing all files

[DipperDolphin]

I have 720 files in my Music folder, however when I hit insert to copy them to the musicbee library, only 300 are added.

When I go onto music in the sidebar, select all, and right click and try to send to library, it does not let me. The box cannot be clicked.

How can I fix this?

Thanks

Figured it out! Went onto library, imported all to inbox, and then into library.
