Drawing block save location

I would like to remove the saved "blocks" from SWE.  I can see the names in the list, but am unable to find where these are stored.  When I create a new block with the same name within a symbol, it will bring the old block version in the symbol when it gets placed in the schematic.  I would like to try to clear my blocks and start fresh to see if this will fix the issue.
