but it is still wrong in the file pathname

Modifying the filename is an additional step.
see the documentation:

Rename Files and Import Tags from Files

Mp3tag provides a variety of possibilities to get tag information from parts of the filename or to rename files based on the information stored in the tag of a file. The base concept behind all converters in Mp3tag is the format string, which describes a pattern or template of a filename. A format string consists of any characters and predefined placeholders or scripting functions. Every placeholder begins with the percent sign %, followed by a tag field name and ends with the percent sign. …

Filenames may reflect some of the tag data - but in general the filename has only the function to allow the operating system to find a file and that the filename is unique.
