I did a copy past on a polygon shape of waterways into a polygon of bottom(ground). Except from some waterways(4) I can see all the other waterways into the ground-polygon. When I select them, or by selecting in the map or by selecting in the table, I can see the shape, but unselected i see nothing.
How can I get to see the other (invisible) waterways as well?

ps all information is already into the table.
(there is question of boundary in the ground-polygon where these waterways run)
