I believe I have met the requirements for the Third Research Depth (Fighter) and (Researcher) achievements. However, the following were displayed when I attempt to unlock the former:
 

Quote

Not enough level 1 clues unlocked from locations with the requited coordinates
Not enough level 2 clues unlocked from locations with the requited coordinates

- noting the achievement requires 40% of level 1 clues and 40% of level 2 clues unlocked

 

And the latter:

Not enough level 2 clues unlocked from locations with the requited coordinates

- noting the achievement requires 80% of level 1 clues and 30% of level 2 clues unlocked.

 

Although it is quite difficult to verify which clues were achieved at each level, it appears quite the paradox that one may unlock of 80% of the level 1 clues but not of 40% of them.

For verification, this were my present research library. I wonder if there is an excess of unlisted "test" research entries which are falsely contributing to the requirements.

Same issue for me.

Quester achievement does work though.

 

Edit: Aksel says Quester achievement is bugged too. It says you need 3 WPs but then error shows saying you don't have 8 WPs. Having spent more than 8 WPs I haven't seen this.
