Pro Tools pencil not working after AAF import

I just got an AAF from an Avid editor, and decoded it. I chose "copy audio media" as opposed to 'link to audio media' so all the audio files are now converted to BWF and copied to the session (not referencing to the original files). Yet, when I use the pencil tool it changes to the grabber tool at sample level edit so I can not use the pencil tool. I am aware that I can duplicate all the files and then it may work but I don't want to do that as I would loose my handles. How can I make the pencil tool work? PT 11.1.2 HDX mac
