KiCad requests to annotate the schematic even he keeps asking me to write down the diagram even though it has already been done

Schematic
1

I’m working in a quite complex project.
It is composed by some nested hierarchical blocks.

I’m stuck because KiCad keeps asking me to annotate the schematics, but:

  1. I did it several times, saving all every time
  2. it does not list anything during annotation (since all is annotated!)
  3. I recursively checked the sch files (using grep) to find any ? simbol
  4. with a bash script I checked for duplicated UUID
  5. running ERC with the unannotated symbol check enabled as error leads to show nothing
  6. I tried to remove the _prl file
  7. I checked the hierarchical paths of the blocks and they seem fine: they are unique and the nested path seems ok

I really don’t want to force a reset of the references since I have almost 10.000 references and a lot of python scripts to position them on the PCB. if the references change it will be a mess!

How can I ask KiCad to show me WHY it thinks the schematic is not fully annotated?

Found out the problem, there was a duplicated reference but the error message was hidden. I cannot delete the post, though. Sorry for the xy problem.

Just mark your last post as the solution and it can be an educational topic.
