"-NULL" presets appearing in Halion Samplefuel libraries?

Wave and Revolution both have a lot of presets that are appearing in the browser with
-NULL" at the end of the name, and those presets don’t work properly. Something loads but it’s a broken preset - the LFO doesn’t work, even if you turn it on and off again or mess with the settings. Anyone else have this problem and find a solution?
I’ve tried deleting, redownloading, removing and readding with Library Manager, rescanning in Halion, etc. All other Halion libraries are working fine.
