I took at look at your collection synced to AnkiWeb, and you actually have 2 presets with nearly the same name –
Those qualify as unique, but I think the search might be stopping at the preset of anking and not seeing the preset of AnKing. Try these things –
- Rename one of those presets (or delete the other one, since it isn’t being used).
- Blank out what’s currently in the “FSRS parameters” field, and the preset-filter field below that.
- Save.
- Reopen the Options and click “Optimize Current Preset”.
