Manage several Journals term lists

If I create 2 term lists for journals, only one of the two is used when an output style defines that Journal Names Format is from an Abbreviation. Is it a bug ?

Let me explain further:

Create a Journal Term list with a term

Full name      Abb1   Abb2   Abb3

Abcde Abc.    Abcd.  Ab.

Create a Journal2 Term list with a term

Full name Abb1 Abb2 Abb3

Xyzkw Xyz.                 Xy.       Xyzk.

Create a reference with the journal name Abcde and another one with Xyzkw.

Create a style that uses Abbreviation 3 as Journal Name Format

The journal for first reference is show as Ab.                            It is correct

The journal for second reference is show as Xyzkw                It is not correct. It should be Xyzk.

It seems that Journal2 Term list is not taken into account for journal name substitution. But it is used for the auto-complete when Journal name is entered manually.

(I have simplified the situation, of course my bibliography is a little bit more complex ! But the idea is similar)

Thanks a lot
