What made my life easier was as you did, I'd go through a Naniwa progression and finish on the 12k making sure that these stages were done right.
Then I'd go to a Coticule with water alone, regardless of what happens I would not use slurry at all at this stage (that's what the Naniwa progression was for). I usually hone on very small hones and I can't look for undercutting, so that's not something I usually focus on.
On these slower type Cotiules I'd easily do 100 laps on water alone. Just some laps on plain water and then to the strop, a Coticule finished edge can always use a good stropping!
I've done years of trial and error and found this the easiest way for me, I used to think I was ""cheating"", but it's the only sure way for me to get the most out of my Coticules where I'm sure all the stages are done right without speculating with slurry and grit/polish. Etc.
What I would try in your case is probably getting the 12k edge finish back on the razor and just go to the coti on plain water. In my common sense that should work.
If that doesn't work something ain't right.
But that's just me, other people will probably chime in with some more/better advice.
Good luck!
