Tooltip displays incorrectly

[TeeDubs84]

I am using a Master Viz to create a custom Tooltip in  my Qlik Sense (Enterprise) App. 

One particular Tool tip is not displaying correctly where others work fine. 

Please see image attached.

All of my Tooltips show white Html table borders around the content. Lookling at other apps, there are no borders and no formatiing issues.

I was using a non standard Qlik Extension "QlikLab - Variable management for bookmarks" -

This seems to cause the issue. I have removed the extension and now my tooltips work fine again.
