Insert block does not insert correct block

We have lots of standard blocks that we insert into drawings.  For some reason, after the "master" block has been updated or otherwise modified, the change does not appear in the blocks from the Open Blocks window (under Blocks to Insert).

How can I insure that the current block is referenced in the Insert Open Block window without browsing to the new(er) block every time?

Thanks in advance.
