Possible Bug when Duplicating an Input Audio Port

While in Options => Audio Ports, if I run [Duplicate] on a stereo input port, I get a mono input port as a result. (i.e. the resulting audio port has a single channel labelled “Signal”).

Performer v3694 x64 on Win10x64

UPDATE: This does appear to be a transient issue. It happened to me about 6 times in a row, then stopped happening. It was happening when the Audio In port I was duplicating was the first in the list (if that makes a difference). I was (of course) changing the name of the port that I was duplicating.

UPDATE2: It then happened on output ports repeatedly on a different host (also Performer v3694 x64 on Win10x64)
