Why was the Bhavishya Malika needed when the Bhavishya Purana already existed?

From time to time, various religious texts are written for the welfare of human civilization under the direction of God.

And some religious texts are also amended. This is done only at a particular time under the direction of God, and by someone who is chosen by God.

The Bhavishya Purana describes the situation of Kaliyug.

The Bhavishya Malika Purana describes the end of Kaliyug, the establishment of religion, the appearance of Lord Kalki, and the Anant Yuga(coming golden age) in detail. This is the last text of Sanatan Dharma.

This series has a set of 185000 texts. In these sets of texts, there is a detailed description of the character of devotees, the generations of kings, the detailed description of the future, which sinful deeds led to the end of Kaliyug, Yug Sandhya, the establishment of religion, the appearance of Lord Kalki, the protection and salvation of human civilization.

Bhavishya Malika Purana is the only text in which there is a brief description of Lord Kalki, the tenth incarnation of Mahavishnu(the supreme).

When will the incarnation of God take place, where will it take place, and where is Sambhal village(place of birth)? Who will be the parents of God? etc.., and how the establishment of religion takes place, all this is described only in the Bhavishya Malika Purana. This is a vital part of Jagannath Sanskriti(culture).

Such a detailed description of Kalki Bhagwan(god), the tenth incarnation of Mahavishnu, has not been given in the Bhavishya Purana or any other religious texts.
