Steps to replicate the issue (include links if applicable):

• Go to https://www.wikifunctions.org/wiki/Special:ListObjectsByType/Z40

What happens?:
The subheader says:

"All Objects of type true/false (Z40)"

The list subheaded as "All Types" ends with
"true/false (Z40)"

What should have happened instead?:
"true/false" is not the label of Z40, but it is Boolean (see https://www.wikifunctions.org/view/en/Z40 )

So it should be
"All Objects of type Boolean (Z40)"

In the list of All types it should also be Boolean

Since we are already here, we can also remove the (Z40) (or file a separate bug for that)
