Custom Filter List Issue

Glyphs
1

So when I make this list filter and set the filter on – suddenly the glyph view only shows the leftArrow glyph (I have all the glyphs in the font), what’s going on?

Works as expected for me in 3.0.3 (3079) on macOS 10.15.7 (19H524).

Is there something typed in the search field?

This was in G2 Version 2.6.7 (1356)
Nothing in seach field. The issue seemed to be the fact that the list had repeated elements, it used to not break the list filter but now it doesn.
