Unable to search for jewels with no level requirement

There doesn't appear to be any way to search for abyss jewels with no level requirement. If you set up a search for jewels with, for instance, max level 8 - you get the expected result. If you try max level 1, however, you get no results. I assume this is caused by them having no level requirements at all, causing the search parameters to exclude them entirely.

As a sidenote, if you attempt to search for max level 0 jewels, the function ignores the constraint completely and gives you every jewel.
