Hello Bastien,

Thanks for your attention.

Can you tell us how do you export?

Through C-c C-e ?

No. If I try that, it is not recognised as a valid combination.

I use C-x C-w when in agenda mode.

Also, please provide a minimal test file with a reproducible recipe,
this will help solve the issue.

Attached.
