Can't label torrents

[Aledosim]

Hello, I'm trying to label my downloads. I select them, touch the three dot menu, then "Edit labels"; add a label and touch "ok". But it don't work. When I access the "Edit labels", my new created label don't show up, neither on the filter of main view. I'm using Tremotesf Android 2.12.1 with Android 10. Hope to help with something. Thanks.
