The guide says "Show only lemmas occurring fewer than 1 times" Logically this guide should reveal no words because 0 is the only integer less than 1. However, it does work at finding single use words.
The item should read something like "Show only lemmas occurring # times or less." Please don't change the function of this setting to match the actual wording. Its behavior seems the most natural to me; if I want word occurrences 50 and under it's an extra step to input 51.
