Can not change custom component line number

A little help please;

We've got a CADWorx custom block library. Not sure if why this is happening now, but some of the blocks don't allow for the line number to be changed. They also don't allow you to access the ISOGEN or CUSTOM DATA buttons (they're greyed out). Basically, it's set somehow to "read only".

Thought that maybe the items were on a locked layer, but that's not the issue.

Any help to get these items to be editable again would appreciated.

Greyed out component usually means its from an older non compatible version of CADWorx.

It should say something like V2012 or something at the top. You can ussualy convert these components if you have compatible specs to map to. I think the command is called convertcwxlegacydwgs or similar.
