It is not the Master that is linking - that is now a part of your new file.
It is the drawings on that master that are linking to the old file still (external link).
Open the Drawing Manager, look for any file that does not have an "Internal" path.
If it is 'Placed To' a master layout, you can then right click it and choose to link to an internal view - assuming you have an equivalent internal view to match.
Or you can open the Master layout and select any drawing on it, right click it and link internally.
Or if you can just delete the drawings and add another new internal view (drawing) in its place.
