Bug in wp block export

When exporting a block, the .scss file is included instead of the .css. I must copy manually every time.
Update (Pinegrow v.6.6 on Mac)

Can you please contact the support (and send us your project) so that we can analyze the situation?

Thank you in advance.

I rebuilded from scratch on second Mac and similar problem.
I will send this second project via email.

Emmanuel thanks for quick respond and first class support.
