Hi @HAWE-MATTRO ,
Sorry about any inconvenience.
Before this issue is fixed, could you please try below workarounds? Hope it helps a little.
1. Please NOT 1) use the legacy CAM job which has excellon outputs in CAM job setting or 2) new excellon output or 3) Generate Excellon outputs based on PCB stackup.

2. Instead, you could use the default example CAM job and Auto Drill.

3. If the CAM job file is from Manufacture, and actually you need NOT the Excellon type Drills, but Auto Drills are OK for your board, you could just edit the CAM job file with any text editor, e.g. notepad in Windows, and change the drill type from excellon to autodrills, then load the modified cam job to generate gerber and drills.

Hope it helps a little.
I will keep you be posted once the fix is ready for you.
Regards,
Helen
