Potential bug in excel charts

We recently upgraded to Cells 4.6 from 4.4 and some of our excel charts stopped displaying correct data. Upon further investigation it looks like the Chart.nseries.categorydata, and .add methods are incorrectly interpreting lowercase column letters. For example, “b23:b50” is getting translated to $AG$23:$AG$50. We were able to fix the problem by changing all our strings into uppercase in code, but somewhere between version 4.4 and 4.6 the behavior of lowercase letters changed.
