Sushant,
Can you tell me if your detail_cr.htmpl form is customized for the form group which the affected role is using? Also are there any CSS or .js files that are specific for that role?
You may want to disable custom forms/js/css files and then re-test it to see if it still occurs.
Outside of that, I am not sure - you may need to open a support case for this one.
Thanks,
Jon I.
