How is the existence of examples of "Hadith Mudtarib" (disrupted Hadith) in Bukhari and Muslim consistent with it being one of the worst types of weak Hadith, as explained by Ibn Hajar?

The people of knowledge have transmitted the authenticity of what the two Shaykhs (Bukhari and Muslim) decisively affirmed regarding the hadiths in the two Sahih collections. A mudtarib (disrupted) hadith is one in which the narrators differ in its sanad (chain of narration) and matn (text), with no possibility of reconciliation or preference. Some scholars claimed disruption in hadiths that, upon examination of their asanid (chains) and narrations, proved to be sound. An example of this is the hadith: "He made sacred what is between its two lava fields," as it was narrated with other wordings. However, Ibn Hajar refuted this by demonstrating the possibility of reconciliation and preference. Similar examples include the hadith: "The two parties in a transaction have the option," and the hadith of al-Musarrat (an animal whose milk has been artificially retained), where Ibn Hajar clarified that the authentic narrations show no discrepancy, and a weak narration cannot invalidate an authentic one.
