掲示板 Forums - The Schedule All button (wrongly) includes everything in search

I found this problem when creating a schedule for studying 四字熟語, so here's an easy way to reproduce this:

1. Create a schedule, and in add materials search for 四字熟語.
2. I wanted to add everything from the list "Common 四字熟語", so I clicked "Schedule All" under that list.
3. BUG: Instead of selecting everything in the list (four lessons totaling 682 terms), it selects everything in the search; over 7,000 terms!
