Corrections for trace features are kernel based and ST01 shows them as string in a field which it can read from the file.
Sometimes ABAP correction features are needed for the STAuthTrace as it splits those file strings into fields for ALV.
This can have the unfortunate side affect that the kernel version is not 100% downward compatible with ABAP based ALV reporting.
This sometimes affects tags (type=xx name=xx bname=xx) if they contain special characters, particularly the character & or the tag && (Eg &NC& or ' ' which ABAP might interpret as a tabulator or double-split.
-> you should check SAP notes for ABAP corrections or open a customer message.
Which ABAP and kernel versions are you on?
Cheers,
