Media Folders view sorting problem

[Ultroman 87]

One of these past weeks, maybe 3-4 weeks ago, after an Emby server update I assume, the Samsung app seems to ignore the sorting names I've set for my folders, using the metadata manager, or it is reading/handling them wrongly. I've just given them sorting names as numbers from 10-22, where 10 should be shown first. The sorting in the view looks completely random, for whatever reason.

 

It works perfectly in the Android app.
