Description

### System Information

Ubuntu 22.04

### LMMS Version(s)

apt

### Most Recent Working Version

_No response_

### Bug Summary

The default file type (which cannot be changed) when saving a preset for/through AudioFileProcessor is .xpf but .xpf is not an available option when trying to load a preset.

### Expected Behaviour

Either make the "All Audio Files" option behave more like "All Files" or add .xpf as an option

### Steps To Reproduce

Save a preset through AudioFileProcessor.
Try to load it through AudioFileProcessor.

(work around is to manually drag the file into the AudioFileProcessor track from elsewhere)

Research direction

Start at the AudioFileProcessor preset save and load entry points and reproduce the reported .xpf file-filter mismatch on Ubuntu 22.04. Check how the save and load dialogs define their available file types. Done means a preset saved by AudioFileProcessor can be selected and loaded through its load dialog.
