Cannot add item to custom collection

[fritzmg]

I wanted to add to videos to a custom collection. So for the first item I chose "Add to collection" in the item's context menu in the web interface, there I left the default "New..." and entered the name of the collection.

After having created that I went into "Add to collection" for the second video - however in the drop down I cannot choose the previously created collection. I also made sure to clear the browser cache and refresh the page, but still I am unable to select the created collection (or any collection for that matter).

Is there something else I have to do in order to be able to add several items to a collection manually?

Jellyfin Server version is 10.10.3
