Gradebook setup not include after restore course

Hi everybody.

I'm using a Moodle 3.11.7 version and I have got a issue when I try to restore a particular course included in a backup file (backup file was make with default configurations).

Normally when I restore any course the gradebook setup is restored correctly but in a particular course the gradebook setup is not restored fine, only main course category is created.

I have compared gradebook setup and course grade settings between this course and other that it  was successfully restored and I found no differences.

I tried to find some solucions but I didn't find anything clear. 

Thanks in advace for any help you can provide. 

Regards, Vicente.
