To fix this, open the Hal Brain Editor, go to the misc folder, open the "names" table, find the name "Pleas" and delete it.
I will remove this from the halbrain.db in the official Hal 6.1 release, but upgrade installs won't touch existing halbrain.db files. So only fresh installations will fix this issue. If you want to keep your existing halbrain.db and fix this just delete the name from the database manually.
