Time Line Picker Web View Broken Graphic

I have implemented the Time Line Picker for OpenHAB

And it works a treat, just 1 one small issue, and its more of a niggle than anything else, it displays a broken image image link in the BasicUI. I suspect its not specific to the timeline picker but instead the webview part on the site map.

The address it refers to is:

http://xxx.xxx.x.xxx:8080/icon/webview?format=svg&anyFormat=true

My Sitemap:

sitemap DJPM_House label="DJPM house" {
    
    Frame {
            Text label="Scheduler" icon="calendar" {
        
                    Frame label="Conservatory Heating" {
                        Webview url="http://xxx.xxx.x.xxx:8080/static/time-line-picker/index.html?ip=xxx.xxx.x.xxx:8080&transferItem=TransferItem1&yAxisLabel=15,6,7&lang=en&states=
                                 off,cool,on,heat&event=no&dark=yes&zoom=no&colorset=555E7B,B7D968,B576AD,E04644,FDE47F,7CCCE5,D486E8&deactivation=true" height=9
                    }
                    Frame label="Hall Lighting" {
                        Webview url="http://xxx.xxx.x.xxx:8080/static/time-line-picker/index.html?ip=xxx.xxx.x.xxx:8080&transferItem=TransferItem2&yAxisLabel=15,6,7&lang=en&states=
                                 Night,Day&event=no&dark=yes&zoom=no&colorset=555E7B,B7D968,B576AD,E04644,FDE47F,7CCCE5,D486E8&deactivation=true" height=9
                    }
            }
    }

Any idea’s how to get rid of the image icon?

Webviewicon="none" ?
