No back items on trench coats/cybertech jacket

[Beef Ninja]

So I was making a character when I thought to myself "This would be a perfect character for one of those cool jetpacks." but when I went to the back tab the only option was the crab backpack, so I messed around a bit and discovered it was because I had the "Cybertech Long" jacket, so I checked the trench coat and that also made them disappear. Although I don't know if this is truly a bug or something that made sense only in the minds of the old developers.

 

Also I noticed another bug with the cybertech long jacket where you can't change the color of the inside of the coat tail without changing it to the trench coat tab and changing them there. Not sure if I should start another thread for that.
