I went to the video
https://www.youtube.com/watch?v=9p3DzUwxI0o&feature=youtu.be & opened the VDH menu. I got what you can see in attached image Variants.png. (Click each image to see a magnified, legible version of the image.) You'll notice there's a bunch of entries. Next you should open VDH's settings dialog. You do that by clicking the little gear icon in the bottom right corner of the VDH menu. You can see it is partially obscured in the attached image Settings.png. This is due to a bug I take every opportunity to point out. It is shameful that this bug has been allowed to persist for well over a year since the first time I complained about it. It is a simple GUI bug. When the VDH menu is long enough, as it is in this case, all the VDH buttons & controls at the bottom of the menu are at least partially cut off, sometimes completely. This sort of inattention to obvious GUI issues is a black eye for the development team (and I probably mean Michel when I say this). Such a simple, basic, fundamental problem should never have been allowed into a product released to the public. Worse, even though you should have dropeed everything to fix this, you have not. Shame. Shame. Shame. In any case, you can hover the mouse over the gear & the "Settings" tool-tip will appear. Then click the gear. This will give you the display shown in attached image VDHSettings.png. Click the indicated control. That will give you the Behavior page of VDH settings as shown in attached image Behavior1.png. Scroll down until you see the settings shown in attached image Behavior2.png. Note the highlighted setting. The default for this setting is that the check box is checked, as you can see in the image from its color. The changed color shows that I have changed the setting from its default. I have unchecked the box. If you leave the check on that box, it will reduce the number of variants you will see in the main VDH menu shown in attached image Variants.png. Look closely at that image Variants.png. I highlight the relevant bits in attached image Indicators.png. I'm showing a blowup of one of them in attached image Blowup.png. Now you can see that the little indicator looks like a lock. This indicates that the variant is locked. You can't access that particular variant unless you . . . I don't know, pay YouTube some money, I suppose. In any case, if you have left the box for the VDH setting "Ignore protected variants" at its default, meaning if you have left it checked, those variants will not appear in the VDH menu.
