Hello, I have noticed that it appears unidict adds support for Tech Reborn dust to the redstone furnace but it doesn't work.

This shows in JEI:

But the machine does not accept any of the dust.

It may be because advanced rocketry also adds the dust and when it unifys them it does this.

I really don't know what is causing this, are you in a server?

if it is showing on JEI, it means that the recipe is there, and if it isn't accepting the dust, it is probably something related to Thermal Expansion.
so it is not an UnIDict issue.
