### Description :
WP allows to select properties by using the option -wp-prop. I have noticed the following:
When selecting a property 'foo' by -wp-prop=foo, sometimes all VCs that belong to that property are verified.
However, when I wish to verify all properties, some VC's of the property 'foo' are not verified.
This might be caused by the fact that the the actual "shape" of a VC appears to depend on -wp-prop.
(I attach an example of the slight differences between a VC that belongs to a certain property "foo" depending on whether -wp-prop=foo is used or not.)
This of course defeats somehow the purpose of using -wp-prop and it would be a welcome feature
if the generation of a VC of a property 'foo' is not affected by "-wp-prop=foo".
### Additional Information :
Is this maybe a problem of Qed?
Also, if there are several ways to generate/simplify a VC, it would be nice if one chooses one that has a higher likelihood to be verified.
