Hey Konrad,
Thanks for the reply. I was using an outdated package of Rhythm’s witch had a document input (got the same result so I updated to the latest version). John has said that this node will check to see which file the sheet came from. (Link to post)
The two views in question do not have counterparts in the current model. I only noticed the error when creating new views with their names. (Views cannot have the same name).
Since views with these names do not exist I am guessing it is grabbing the linked views.
I am using the BIMorph package to collect all sheets in the linked model. It does have a set of nodes designed for this.
