Pilotwings 64 Birdman Render Issue

[TheRookMan]

So I was playing Pilotwings 64 for the first time since I thought it looked pretty nifty. The game seemed to be working pretty damn well. Eventually, I wind up finding a star that activities the Birdman mode. However, the Birdman model is somehow combined with the hang glider model of another one of the playable characters. In the example photo I posted, Lark is using the Birdman suit whilst being combined with Goose's hang glider model.

Because of this, Birdman mode is pretty much impossible to enjoy since there's a huge hang glider model blocking my view.

Even if I don't get answer for how to fix this, I at least want to know how the hell this is possible. Easily one of the most bizarre emulation hiccups I've encountered.
