Smart Glyph category missing in 2.5b?

In 2.4.2 glyphs with a name starting with _part show a category of Smart Glyph, but the same files in 2.5b (1084) don’t show this category anywhere. I have a plugin checking for this category so the check fails in 2.5b. I’ll just check for names with _part instead, but is this category supposed to be missing?

Fixed it.
