We have upgraded to the 3.12.1 version recently and started noticing that the charts are putting a text 'abcdefhiklmnopqrstuvwxyz'. Going back to 3.12.0 seems to show the charts fine.  Looking up the fusioncharts.js. I see that the in line 526 and 989, there is 'document.createTextNode("abcdefhiklmnopqrstuvwxyz")'. Anyone know why this is added or what is the reason that is causing the text to show up now. Attached is a screenshot.
