Accept decline buttons disappear for the editor

Hi,

I am using ojs 3.1.0.1 . In editorial processes of my journal, somethings go wrong.

I have 2 editors in my journal. These editors have journal manager, journal editor, production editor, section editor and etc. roles.

After assigning an editor, buttons such as accept, decline and etc. in review tab disappear for this editor but the other editor can see and use these buttons.

I tried this period in PKP web site using demo test drive journal. In this test journal, assigned editor can also use buttons such as accept, decline and etc. in review tab.

I also want to be able to use all buttons in review tab for assigned editor. How can I solve this problem in my journal?

Thanks,
Arif

I solved that in role settings.
