FCCS Amount override not working on some intersections

I raised a similar query on this last November:

FCCS Amount Override not working second time round — Cloud Customer Connect (oracle.com)

However, this issue is slightly different to the discussion on this post.

I'm trying to post an override adjustment using smartview to adjust a value in 3 parent entities:

GFH0C is a child of GGh3C, which in turn is a child of GHH3C

• GHH3C
  • GGH3C
    • GFH0C

I'm using the FCCS_Amount override in each entity to clear the balance on a GL code (925000).

I've done this before several times and it has worked in each case however, the override adjustment isn't working at the lowest entity in this hierarchy i.e. GFH0C.
