Uppercase category on a single line?

I have an uppercase font that is currently just 26 letters plus a few alternates. Instead of wrapping, all of the glyphs show up on a single line. I choose “All” or “Uppercase” with the same result. They don’t wrap, so the ones that go wider than the window are hidden. I’m not sure if it helps to know that I converted it from .vfb to .glyphs using Glyphs Export.py. I was able to fix the glyph order, but I nothing I’ve tried fixes this. Do I have something set wrong?

I closed the font and opened it again. Now the glyphs wrap as expected.

That is fixed in the latest cutting edge version.
