Daniel Chap 8 little Horn?

Daniel Chap 8 always confused me. The last (4th) Beast was detailed in Chap 7 and the former 3rd beast detailed in Chap 8. Both detailed beasts had a little horn coming up later but from different scenarios of previous horns. However Chap 8 explains the 3rd Empire (Chap 7 Leopard) instead as a Goat and in more detail. It's little horn rises out of 4 horns (Generals) taking over (per history) Alexander the Great's empire (at his death). But this little horn isn't said to subdue any previous horns but rather it waxed exceeding great to the south, east, and pleasant land. If one examines history the first sections of Chap 8 seems to be about the Seleucid Empire's Antiochus Epiphanes IV. But the latter part of Chap 8 also seems to go beyond Seleucid's Epiphanes IV and details more in line with the timeline and happenstance of the 4th (final) beast of Chap 7(?). Other than this said implicit latter section expansion Chap 8 does not specifically mention the 4th beast empire included Daniel Chap 7. The Seleucid Empire encompassed a good fraction of the same area as the Eastern Roman (4th beast) Empire. But it's confusing to see the little horn out of the 4 horns go on in the latter section of Chap 8 to sound synonymous with the little horn of the Chap 7's 4th beast which subdued 3 of it's previous 10 horns. Unless Chap 8 is not referring to the 4th beast at all (timeline or premise) and verse 11 is referencing Israel of Christ's earthly time. And verse 23's latter time is referencing the same? I.e. making Chap 7 more about the end of the times of the Gentiles and Chap 8 more about the cutting off of the messiah and Israel being scattered until the last days?
