ASM logout and AddToCart is not working..

Hi , We have migrated from 5.7 to 6.3 . After the migration , we have installed 'assistedservicestorefroint' addon . I am able to login as an asaagent and logging into the customer session as well. But I am not able to click on the session timeout and Logout button . These two buttons are visible but are disabled. I do not have any clue why this is happening . Could you please give me an idea to know why this is happening. Has any one already faced this issue.

I have attached the screen shots for your reference.. Thanks in advance..
