Homepage Image can not update in OJS 3.4.0.4 version!

Hello !!
I am using OJS 3.4.0.4 version. When I want to update the Homepage Image in Manuscript (Default Child Theme), I get the error: The about-bicm block can not be found. Please make sure the plugin is installed and enabled (The form was not saved because 1 error(s) were encountered. Please correct these errors and try again). What is the reason behind it and how to solve it or can change the Homepage Image? Please co-operate me.

With Thanks
Ivan M Rahman
