What planes are these, and how can i hide them?

[Valakas]

Hello, thanks in advance for helping.

Somehow i got these planes to show up. Does anyone know what they are and how i can revert that change?

Also, I can't get the list of parts to be right. When I add a list of parts it appears a huge list with lots of file names, instead of the component name for example, instead of "Return Pin" it shows COPO_TOOLING_EJECTION_166

Thanks in advance again

Try this key combination ctrl+w and use (-) on datum's. You can also set reference set to true, or hide layers 2-255.
On the second post, You can add another column and select description field, so You will see "return pin" in this column.

With best regards
Michael
