Exporting use cases to Excel does not export all use cases

After exporting to excel some use cases are missing.

Can you provide more information?

for example,

the missing use cases do not exist on the UseCaseDiagram(s) which you selected on export dialog? (as screenshot)

one more possible case.

If none of the above cases, please try to provide more information to us for finding out the problem. Thanks.:blush:
