Import of a Gerber drill file to Eagle does not work

[Nietendengler]

Hello @ all,

I´m a newbie with Eagle and i need some help with importing a Gerber File to Eagle. I know how it generally works, but i have trouble with a special project i´m working on. Whenever i try to import the drill file from Gerber to the drill layer in Eagle there is nothing to see. Consequently there is also no CAD data to export and i can´t drill the PCB Board. (It is not possible to attach the .DRL file here, sorry.) All other files behave normally. I also was able to import gerber drill files from another project. What am i doing wrong? Here a picture of what the import adjustments look:

And here a picture of how the PCB Board looks (only the board itself was imported before, no lines)

No drill points to see. (The visibility of Layer 44 drill is activated...)

Can anyone help?
