So today I discovered that the organ instrument from the vampire pack shows singing skill functionality in the catalog, but when trying to let my Sim sing a song on it, the singing tab is missing. It only shows on the piano. My Sim has max singing, piano and organ skills and can sing on every other instruement that supports singing, but not so on the organ.

I use CC and mods, but as always, I tested without any CC/mod to make sure before posting here.

The organ simply has no sing a song tab to chose like the piano does. I even checked the organ with Sims 4 Studio in the ObjectTooltipTags and the singing skill entry is there.

Here are some picture proof. It's in German since I play in German but I'm sure you get what I'm talking about.
