VH band bug in Terrain Correction?

When I am doing Interferometry processing for Sentinel 1 products, the final step (Terrain Correction), outputs a “displacement_VH” band, even though at that point there is only a VV band in the imagery. I have gone back and confirmed this multiple times and am not sure where this is introduced. There is no sign of a VH in the product until this last step (Terrain Correction), so I’m guessing that this band name is hardwired into the code, or deciding it’s VH in error. This has happened every since I’ve been processing S1 for the last year.
