ICSD data update on Material Project Database

Hello. I am looking for ICSD labelled compounds in Cu-In-Te ternary system. I found two compounds in MP CuInTe2 and CuIn5Te8. When I check ICSD database directly, I found an additional compound added in 2017, Cu3In5Te9 [Titled: Structural characterization and optical absorption spectrum of Cu3In5Te9 ordered defect semiconducting compound]. I am wondering why it doesn’t show up in Material Project Database. Because I use icsd_ids tag from MP api to get compounds registered in ICSD, I would like to know if these two Database are in sync. Thanks in advance.
