Nice model!
There are two lines (series of edges) that somehow appear to be profiles and that need to be fixed into (hidden) edges between face segments (so no thick profiles). They border the surfaces between flat highest floor level and curved surface towards the middle leveled bowl and further down, between this curved surface and the flat floor of the middle leveled bowl. (I hope the description is clear).

Thanks for input, found it!
