Oath Ceremony / No Permanent Resident Card

[jjj0704]

I filed an N-600 back in February, sent required documentation, was asked for more and sent additional information - including my passport - which I applied for at the same time and received back already. I then received an Oath Ceremony notice.
I noticed part of the ceremony includes returning your Permanent Resident Card. I don't have one. I never did.
Is that an issue?
