You should show some of the code generating the offending "titles". Preferably with some example data or using a SAS data set like SASHELP.CARS or SASHELP.CLASS so we can see something similar to what you are doing. Since this involves Excel then all of the options used on your ODS EXCEL statement need to be shown as well.
First, I don't think you actual mean title but maybe "column header" which is quite different.
