Sidebar conflicts with the vertical line

The sidebar is wrong positioned (across the vertical line).
How can I move it to the right position?
(OJS 3.1.2, Manuscript theme)

Hello @Spaik,

Have you made any customization (on your CSS) that could have affected this area of your journal?

Kind Regards,

@pmangahis, thank you for your answer (question :).
I installed the last version of OJS and now have no problem with this bug.
