Why can't I craft this theme?

Ok, so I've been playing FS for quite some time now and crafted a few room themes.

However, this one I'm stuck on. As you can see, I have the materials and the caps, but somehow, I don't have time.

On the other side of the vault I have people crafting a legendary weapon for 10 days - no complaints there.

I am playing the PC version in normal (not survivor) mode.

So what's going on with this theme?

yes seems to be some kind of glitch, just restarting the game seems to be available again.

I think it was some kind of glitch, I booted up the game today and I could craft this theme just fine!
