What they mean by "unfillled conditions" is a condition that is stated on the face of the CoPR, like complying with medical surveilance.
The residence obligation (RO) of every permanent resident is completely different as it is an ongoing obligation. In the first five years, it simply requires that you can show that you (or your child in this case) will be able to stay in Canada for two years before the 5th anniversary of becoming a permanent resident. However, the citizenship program is not concerned with RO violations unless there is an open investigation by the immigration side of IRCC or the CBSA.
