Unable to set default print format for POS Invoice

I have set the default print format in Customize Form here

But it’s still using the standard one. I mean in this screen

It works fine when selecting from the POS Invoice List. But I need it to work from the POS screen for my client

This is the POS app view. You selected print format is POS invoice form view.

How do I set the default print format for the POS app view?
