Would that be three-bond coupling between one N and the H's on the other N?

Subject: AMMRL: 15N and 1H spectra of 15N-labeled urea in DMSO
Hello All:
I recorded 1H and 15N spectra of 15N-labeled urea in DMSO.
Both 15N-decoupled 1H and 1H-decoupled 15N spectra have single peak.
Without decoupling, both 1H and 15N spectra show a small splitting of ~4 Hz (see attached pictures).
Does anybody have an explanation of the splitting pattern?
Thanks,
