SEP 3, switching through presets using the keys

switching through presets with the up/down keys does not actually work, please fix this bug

Do you find that it works if you click on another preset with the mouse before trying the arrow keys? This has been my experience.

this works one out of five times

You have Nik Collection 4.0.8? (The initial release was 4.0.7.)
