Cue Type Selector works only about 70% of the time - known bug?

This is in Traktor 4 (but it's been like that in 3). I've assigned the Cue Type Selector action to a few buttons, with Interaction Mode set to Direct and then the values (Fade In, Load, Fade Out, etc.). [See fig. 1]

When I create a new Hotcue and then try to use them, it only works a bit more than half the time. About every third or fourth try, the text in the Cue Type dropdown in the Track Deck will say the correct, new type, but the Cue itself will still be in the normal blue style [see fig. 2], and if I load the track in a deck, it will be a regular Cue again (even the text in the dropdown).

This behavior is independent of how quickly after the creation of the cue I try to set its type, or even whether the cue was created in the same session.

Is this happening to anyone else? Is this a known bug?

Are there workarounds for it? Can I fix it somehow? I am going through my collection and adding a ton of cues, and it's a constant source of pain…
