Bug in search results for 4K vertical videos. (4k video filter)

I upload vertical videos in 4K and have noticed that my files are displayed with the following dimensions: A bug in the search results for 4K vertical videos.

HD: 1080 × 1920 pixels

4K: 2160 × 3840 pixels

However, when I apply the “Vertical Video” filter and "4k filter" in Adobe Stock search, no my videos appear. 

The videos I do see under that filter are listed as:

HD: 1080 × 1920 pixels

4K: 3840 × 2160 pixels

Suppose this is all "old vertical" videos. The 4K dimensions shown in the filtered results appear to be in landscape orientation, which seems inconsistent with the “Vertical Video” filter. I’m concerned that this may be why my vertical 4K videos are not appearing in those search results.

Could you please check whether my (and most another) videos are being classified correctly and whether there is an issue with the search filter or the way video dimensions are displayed?

I.e., if you don’t check the “4K” option, my videos appear in the search results, including via the “vertical video” filter. But if you check “4K,” only older videos will appear in the results. 

Please add “vertical video 2160 x 3840 px” to the filter.

Thank you!
