This is quite a weird bug. It is worth going to your steam library. Right click on the SWTOR icon in the games list. Select properties, under which you can find local game files. You should have an option which says "verify intergrity of game files". Hopefully, this will fix the issue.
I have done a repair as that is always a good place to start, but with no luck this time.
I have also tested it on another PC and on a different account, but the bug is there in these cases, too.
I don't think it is a bug on my end. It may be a possibility that male chiss JK was forgotten when the colour was added, originally?
