The English word "Self" used in Advaita translations (and all Hindu philosophies and their derivatives like Buddhism) and Western Philosophy mean very different things.
In Western Philosophy they are synonymous with "Self-Identity/Ego" etc.
In Hindu philosophy, the basic idea of "Self" comes from the "Samkhya System" (see https://en.wikipedia.org/wiki/Samkhya) which is what is followed by/built upon by other schools of Hindu Philosophy. In this model, "Self" aka "Purusha" is immutable and untainted/undifferentiated pure Consciousness. In Advaita it is known as "Atman". It is "Prakriti", the other aspect of reality which is mutable, that gives rise to "Buddhi"(Intelligence), "Ahamkara"(Self-Identity/Ego) and "Manas"(Mind).
You can see now how confusion arises when people use the same English word "Self" to describe different things in different contexts.
