3D boxes not displaying for some platforms in big box mode

[zjmullan]

When in the desktop mode, I can switch to 3D boxes and view them for each platform.  However, in big box mode, the 3D boxes display for some platforms and not others.  For example, it's working for the PS1 but not the N64 (both are using Retroarch).  I have tried force populating, restarting launchbox and PC, and reloading cache.  None of them work.  Even worse is I used to see these missing 3D boxes up until one of the recent updates (9.6 I think).  Any help or ideas would be much appreciated.

Not sure why it would have changed, but if you go into the options in big box, then controller buttons, you can assign a button to switch images.  On the platforms that do not show the 3d box art, press whatever button you assign to that switch option and press it until you see the 3d box art.  I tried to see if the global option for view image type would change them all, but it didn't seem to for me, so that's why I'm suggesting this method instead.
