Hello, you can try to rename the "User" directory in the configuration folder to create a new "User", and then try to create the preset. Or you can also try the Beta version (with an independent configuration folder)

Because having the user order recreated helped. So it seems to be a bug.

I tracked down the root cause and opened a fix in PR #10875.

Root cause: In PresetCollection::load_presets(), when a user preset's inherits parent can no longer be found (e.g. a system preset was renamed in an update), the preset is silently skipped with continue. The file is still on disk but the preset never shows up in the UI — it appears "gone".

The workaround of recreating the User directory works because fresh presets reference the current system-preset names, so the parent is always found.

Fix: Instead of skipping, fall back to the built-in default config and log a warning. The user's saved values are still applied on top of the default, so the preset remains visible and recoverable.
