Trailers not getting uploaded for Japanese dramas

This is still an issue: https://mydramalist.com/54595-nibiiro-no-hako-no-naka-de/trailers/17237

But nothing here: https://mydramalist.com/54595-nibiiro-no-hako-no-naka-de

Since users can't access trailers from a drama's page unless they click on the green button, this is not good.

Trailer uploaded at least 3 times and still doesn't show:

 Ji-N:

Did you mark them as primary?

Did I have to? :/

 Ji-N:

Yea, that would make them as the main one to show up

I don't remember doing that in the past though.  

 Ji-N:

Something might have changed but it does require to check as primary.

Well... can they be edited and set as primary? https://mydramalist.com/trailers?page=2

Because I'm certainly not downloading 20 trailers again.

 Ji-N:

Of course, I thought you have the ability to set them as primary again.

There's no edit button.

I can't set it as primary
