[rules-users] Guvnor problems...

I am working with Guvnor/Drools 5.5.0, jBPM 5.4.0 on Win7 64 bit, JBoss 7.1.1

First Problem:
1.  I have a rule in the global area, e.g., Rule1
2.  I create a new rule in a package by importing Rule1 from the global area
3.  I realize that I imported the wrong rule.
4.  How do I remove Rule1 from the package?  If I archive it from the
package, it also archives it from global, which I don't want to do since it
has been imported into many other packages.  If I archive it from the
package anyway and then restore it, it reappears in the global area, and
also in all of the other packages that it was a part of.  The only thing I
have found that works is to copy the rule, archive it, delete it, and then
import the copied rule into all the packages where the original rule
actually belongs.

Second Problem (which I got into by trying to deal with the first one
above):
1.  I have a rule in the global area, e.g., Rule2
2.  I rename Rule2 to Rule3
3.  I also have a different rule in a package named Rule2
4.  I archive and delete Rule 2 from the package, and it no longer appears
in the archives, nor in the package.  I save the package, close it, stop and
restart JBoss, and check again, and it is not in the archives nor in the
package.
5.  I try to copy Rule3 from the global area to this package giving it the
name Rule2 (the same name as the rule I archived and deleted) and somehow
Guvnor thinks Rule2 is still there.
6.  I get an error (apparently Guvnor thinks the rule is still there):  
Error
