I have no permission to some documents numbers

Hi all,

I have problem to see some documents on demo database.

For example in Purchase order I can see only documents from 1 to 267, and then 422+. When I click left arrow on document 267 I get document 422, rest is skipped.
When I use drag&relate funcionality I can see the documents exists, but when I click them, I get error "you are not permitted to perform this action; authorization path".

I have regular user with all authorisations and proffesional license(?).
Super user can see them.

Is there any funcionality to restrict specific documents only for some users?
