Topic:
Why does seismic class not display in the Seismic volume deletion window?

Description:
 

Solution:
Most likely, the seismic is shared seismic. 

1.) To remove it from your project, unshare it in DataManager > Seismic > Share.
This will break the link that displays that class of seismic. 

OR

2.) If you want to completely delete this seismic from your project, go to
DataManager > Utilities > Delete and toggle 'Item type' to 2d or 3d surveys,
select survey to delete, and click 'Delete'. Next, toggle 'Item type' to Seismic
classes and select the class of data from the 'Unused seismic classes' window
and 'Delete'. !This will also delete all interpretation for the deleted survey.!
