What was reported Nigel was:

"Sir Alex Allan’s findings, based on the Cabinet Office investigation, concluded that Patel’s approach “amounted to behaviour that can be described as bullying” – noting instances of shouting and swearing – and decided that she had breached the ministerial code, although he said her actions may have been “unintentional”.

So the man in charge of the report quite clearly states her action WERE bullying and had broken the ministerial code but tempered that by saying her actions MAY have been unintentional.
