This 2003 paper by the North American Orthodox-Catholic Theological Consultation, "The Filioque: A Church Dividing Issue?: An Agreed Statement", goes into much greater detail and nuance about the filioque and how it differs (if at all) from Orthodox theology: https://www.usccb.org/resources/filioque-a-church-dividing-issue.pdf https://www.usccb.org/resources/filioque-a-church-dividing-i... TL;DR: It argues that the filioque is consonant with well-accepted Eastern Orthodox theology, but also recommends that it be dropped from the Latin version of the creed in the interests of ecumenism. There's always been alot of shared doctrine between all the (little-o) orthodox churches--Western, Eastern, Oriental, Syrian, etc--that was left out of the Nicene Creed. The creed was never meant to be comprehensive/exclusive, only the minimum necessary to refute perceived contemporary heresies, similar to earlier versions of the creed and the creeds it was derived from.
