BUG: Grid Advanced Search Double Select field

Hi.
I use “Double Select” fields in my advanced search with fields added manually. See printscreen #1
This was working very well with 9.4
I upgraded to 9.5 and I added a new search field as “Double Select” (exactly as printscreen #1)
It does not save the key field anymore but the display field.
To make sure of this, I just switched the field type to a simple “Select” (see printscreen #2) and I kept the exact same SQL statement.

  1. If I leave the “Multiple Values” set to “Yes”, then same bug. Display field is saved.
  2. If “Multiple Values” is set to “No” then key field is saved.

This bug appears only when we use a “manually added” search field. If I use a field from the grid SQL select, then it works properly.
Please SC team fix this bug.
Thanks a lot.
