Merge derived table loose links

Greetings,

Let’s say I have a chain of derived tables
A => B => C
=> D
If I merge the derived table B from A, then I loose the link between B and C - D and I get B [Deleted]
As far as I remember, before EM used to keep the links, whatever the number of split or merging I did.
Did I miss something ?

Regards
