Draw table lines

Hello experts,

I have an issue with the final output of my table. The lines of the table aren't drawn entierely. I highlighted them with red color on the picture.

Here my code:

CLEAR wa_bilan.       ULINE /(120).     FORMAT COLOR 5.     WRITE :/1  sy-vline,30 'Assets'  ,               60 sy-vline,80 'Liabilites' ,               120 sy-vline .     FORMAT COLOR OFF.     ULINE /(120).   LOOP AT wt_bilan INTO wa_bilan.     WRITE: /1 sy-vline,10 wa_bilan-actif , sy-vline,35 wa_bilan-mta , 60 sy-vline, 70 wa_bilan-passif, sy-vline,95 wa_bilan-mtp , 120 sy-vline .     AT LAST.       SUM.       ULINE (120).       WRITE: /1  sy-vline , /10 'Overall Sum',                  wa_bilan-mta UNDER wa_bilan-mta, 60 sy-vline, wa_bilan-mtp UNDER wa_bilan-mtp, 120 sy-vline .        ULINE /(120).     ENDAT.   ENDLOOP.

Thanks for your support.
