Damage Type changes to untyped when dragged onto character.

[Ascalon]

So my PArty loves to roll their own sving throws when being attacked. I saw a tutorial video a while ago that you can just roll the damage in the chat window and then apply the damage via drag and drop. As you can see in the screensho I attached, the fire damage our Tiefling-Lady made changes to "untyped", so the dwarves' Ring Of Fire Resistance does not half the damage.

Which ruleset are you using?
Are you using any extensions?

It's 5e.

After a short check it looks like an extension is the reason for it. I'll see into it. Thanks for the hint!
