Bug in the Sequence of Partners

Hi all
There is a problem:
if you leave the item « Generate sequence for partners » enabled in the Apps settings → Base → Configurate, then when we creating a partner, the word « null » appears in it - an example:

If you switch the view of the list of partners to tabular, the word « null » disappears.
If you turn off « Generate sequence for partners », the word « null » disappears.

Has anyone experienced this?
