Did you save this preset yourself? I so, did you update firmware since then? Otherwise, I don't really have an explanation. Can you save something to this setup slot?

I can confirm this issue in Class Compliant mode under Manjaro Linux. OP's video demonstrates the exact steps I've attempted: Storing a new preset at the device appears successful, reporting "Done." Loading any preset fails with "invalid!" message whether a new preset is saved in CC mode at the device or under TotalMix on Win7.

Hi Matthias thanks for the reply.

My unit is confirmed damaged. Reverb and echo don’t work, they make a crazy sound when I try to use them. Durec doesn’t work either.

Why did you ask about reverb? Does that functionality share the same ‘process’ (I don’t know if that’s the right word) as the snapshot function? It would be helpful to confirm which functions share this besides durec and send effects, so there are no more surprises.

This unit still meets my needs. All the preamps, converters, ins and outs, eq and dynamics, they are all working just fine.

Yes. Have you watched OP's video? In any case, reverb doesn't appear to work for me, either.

I'm looking at purchasing a not-inexpensive optical preamp to expand inputs, can I safely assume that ADAT lightpipe will NOT be affected by this issue? It seems to be the only way I can accomplish anything approaching recall if setups can't be loaded.

Maybe I don't understand how setups work? I assumed that however the unit was presently configured would be stored, is that not right? It was my impression that, for example, if I set the gain of mic input 9 to 32dB and store to preset slot 1, then change the gain to 33dB and load preset 1, the channel will be set back to 32dB.

Thank you, Matthias. No regrets here, the UFX was the last interface I've had to buy after a series of prosumer disappointments that didn't last a fraction of the troublefree years I've had with this unit. I've recommended RME many times over the years and will continue to do so.
