Problems with vertical footage

Hello everyone. Recenly I've uploaded a few vertical videos, in full compliance with the requirements (2160х3840, 9x16, ProRes422). Footage was approved, but for some reasons Adobe Stock don't recognize them as vertical. When I click on shot in search page it opens as true vertical, HD resolution shows as 608x1080 but 4k as 16:9 3840x2160. Also, the file is not shown in the search when the vertical orientation filter is turned on. And preview on search page looks also very strange. Any ideas?
