Preview duplicates left glyph *after* navigating past a kerning pair with a dotted glyph name

Glyphs

When I navigate through the kerning pairs in the Kerning window using the arrow keys, the preview behaves incorrectly after I land on a pair where the right glyph has a dot in its name (e.g. o.001).

Example:

  • Pair: K-o → Preview: Ko
  • Pair: K-o.001 → Preview: K/o.001
  • Next pair: K-p → Preview: KKp ← :red_exclamation_mark:left glyph is duplicated

From this point on, the left glyph gets duplicated in the preview for every subsequent pair.
If I keep navigating through more pairs with dotted glyph names, the preview line keeps growing longer, as more copies of the left glyph are added.

What version of Glyphs do you have? It should be fixed in the latest cutting edge version.
