Click to see the data option in embedded report does not always appear

Hello
 
Users have reported that on viewing a Zoho report embedded in a web page, they cannot always see the 'click to see the data' option. I have tested this report in design view and I can indeed view the data behind any of these data points. I have also tested it in IE8 and it seems fine there but however I cannot see the option in Chrome at all.
 
Can you point me in the right direction as to what I can check?
 
Regards,
Sandra.
