This appears to be a timing issue while changing the filtered card name quickly (re-applying while it's still doing the filtering operation for the previous value). I will add some synchronization code to keep this from happening, which will be deployed in a future release. It seems edge case enough that it doesn't require its own release, though. If I see it come up again, I might bump up its priority.

Closing this issue, but will keep an eye out for similar ones.
