Can you please show us a [screenshot](https://community.mp3tag.de/t/hints-for-asking-support-requests/56190#use-screenshots-to-exemplify-the-issue-2) to see how you use this type of Action?

Have you checked Alt + T to see if multiple fields with the same name have been created?

BTW: The Action "Split field by separator" does not work for \_FILENAME (included in \_ALL), because it only splits the content of tag **fields** by separator, not a filename (nor a directory name).

### [Special Fields](https://docs.mp3tag.de/actions/replace/#special-fields)

- `_TAG` covers all tag fields
- `_FILENAME` denotes the file name of the file
- `_DIRECTORY` denotes the parent directory of the file
- `_ALL` contains both `_TAG` and `_FILENAME` (not `_DIRECTORY`)
