Bug: Font window filters stacking incorrectly

Over time selecting different filters in the font window causes them to stop displaying correctly. It seems like Glyphs is applying previously chosen filters in addition to the currently selected filter, and as these filters stack up, Glyphs is unable to do it logically. For example, right now I have one filter selected but I am looking at a long series of group of one or two glyphs that alternate between Symbol and Punctuation rather than just one group for each. To fix the problem I have to close the font and open it again.

There is some consistency to this. If I have two fonts open with the same character set and choose the same filters the same result occurs in each. I have this problem in 1.2.2 and 1.3.6.
