Bug with AddBGVideo

Description
windows sdk function AddBGVideo adds the file as image file and not as video

Which version?
Latest v5.2.42037.1112

To Reproduce(If applicable)
Steps to reproduce the behavior:

  1. use AddBGVideo to add a video
  2. use GetBGVideoList to fetch list, find its not there
  3. find it with GetBGImageList

Additional context
if you take the video from GetBGImageList and use UseBGVideo(pImage) with it it does work , but its annoying because i need to reliably fetch my added videos and they get mixed with images
