Unable to revert operation in fork

[ethanbass]

What happened just before the problem occurred

I made a fork of one of matej's spectra (https://spectralworkbench.org/spectrums/72260), but when I tried to revert the data, starting with the most recent operation (in this case, it was the smooth function), I get an error message saying, "Operation could not be deleted because it is not the most recent operation to this spectrum. Deletions must occur most-recent-first."

Hmm, very odd. I actually forked your spectrum, and was subsequently able to delete smooth on my own. Can you try again, first forking your own spectrum (since I've now created a dependency on yours, so you won't be able to delete smooth for that reason unless you fork)
