I have a "change price" button on some apps but not on others

As the title suggests, is there a reason for the little “Price change” button to be in some apps/themes and not on others on the “apps” tab ?

This one hast it
Yes prob

This one doesn’t
No prob

It makes me wonder if that could be some sort of suggestion that the app is overpriced.

I’ve only seen that when an app is under a discount?

That might not be the case exactly, I have a recently released theme that has it and one that has an active discount that doesn’t have that button.
