After being a Brahmin son, why were the belongings of Kshatriya in Parshurama?

All of us know that Lord Parasurama was a Brahmin. But the conduct was like their Kshatriyas. Even when Brahmin was a son, why were the properties of the Kshatriyas in Parashuram,

Maharishi Bhrigu's son Richik was married to Satyavati, daughter of King Gadhvi. After marriage, Satyavati solicited the son for her and her mother from her father-in-law Maharishi Bhrigu. Then Maharishi Bhrigu gave two fruits to Satyavati and said that after the ritual bath you should eat these fruits after embracing the tree and the mother of your mother Peepal tree.

But Satyavati and her mother accidentally made a mistake in this work. Maharishi Bhrigu came to know about this. Then he told Satyavati that you have embraced the wrong tree. Therefore, even if your son is a Brahmin, he will be of Kshatriya qualities and even if your son's son is a Kshatriya, he will behave like Brahmins.

Then Satyavati prayed to Maharishi Bhrigu that my son should not be Kshatriya qualities even if my grandson (son's son) is such. Maharishi Bhrigu said that it would be like this. After some time Jamadhi Muni got born from Satyavati's womb. His conduct was similar to the sages. He was married to Renuka. Muni Jamadgri had four sons. Among them Parshuram was the fourth. Thus, due to a mistake, the nature of Lord Parashuram was similar to the Kshatriyas.
