Do your processes and procedures allow you to to conduct verbal reviews of issues and take corrective actions? I do agree with you that you have identified some problems with your process and the proper completion of forms.
If you believe these are true non-conformances, but your documented processes allow this to happen, then it would be a good idea to modify your processes accordingly. Otherwise, you have identified a gap between the documented and practiced processes. These issues should have also been identified through the PPQC process and work product audits.
Also, since the sub-practices are an informative component, they provide additional material to help you understand the intent of the Specific Goals and Practices. There is no expectation that the sub-practices have to be implemented. Therefore, the situation you described really has no impact on PMC SP 2.3 Sub-practice 1.
