Secret to creating files for HyperDeck Studio Mini playback?

I've been trying all day to create a file that will play back on my HyperDeck. No luck. Trying to use my Lower Third capacity but the HyperDeck won't read any of the files I'm making.

I'm using Fusion Studio Pro and ProRes 4444.
1080p@59.94.
HyperDeck Studio Mini.

What's the secret sauce?

Edit: I changed my Output Color Space to NTSC (1953) RBG and success!

Sorry for the double post. How do I delete?

Edit: NVM, found it. That little X is really small on my phone.
