Pinegrow is rewriting my template meta data

When I am creating template with Pinegrow, my style.css is acting weird.

I have created my own metadata for template, as seen below. But Pinegrow during export creates another metadata section above my already created metadata.

I also do not understand, why it sometimes add to coments part of my CSS, as you can see “.divider” which is commented.

Have I to use any “control sign” that will tell Pinegrow, where my metadata is and do not remove it?

When clicking “Edit more project settings”, there is only one template meta, second is writen during export, but why.
But also this part is behaving weird, while it commented my first CSS rule “.divider”
