What is the meaning of "ذكَرَه الهيتمي في الزواجر" (Al-Haytami mentioned it in Az-Zawajir), written below the classification of the Hadith?

The last sentence's meaning is clear: it reports that the author mentioned the hadith (definition) in "Az-Zawajir 'an Iqtiraf Al-Kaba'ir" by Ibn Hajar Al-Haytami. This book contains both authentic and weak hadiths, and the mere presence of a hadith in it does not signify its authenticity or weakness. Most of its hadiths are authentic. It is not a book of musnad hadith; rather, it transmits from earlier works. To ascertain the degree of a hadith found therein, one should not suffice with its mention in this book, but rather refer to hadith books that clarify the degrees of hadiths, such as those on takhrij and defects. Muhammad ibn Darwish ibn Muhammad Al-Hut Al-Beiruti indeed criticized him for including some fabricated hadiths.
