While changing the reader signature a bug was introduced that the sheetnames were incrementally appended to the variable name, instead of to the workbook name. So a file File.xlsx with sheets Sheet1 and Sheet2 resulted in variable names File.Sheet1 and File.Sheet1.Sheet2.
Stub bugreport, will append to later.
