Express Checkout automatically active sometimes why?

Hello guys i use the Theme“Dawn“

My target was to deactivate the Express Checkout. So i try it with this code:

main-cart-footer.liquid:

under the button

{% if additional_checkout_buttons %}

{{ content_for_additional_checkout_buttons }}

{% endif %}

I thought it worked perfectly but in the last day i checked up and it was sometimes enabled.

Not always but sometimes

If i set a product in my shopping cart and klick the button “Safe Checkout”

in the end is the express checkout active (Look the picture 1)

When I repeat the process, Express Checkout is disabled.

But if i delete history/Cache then is the checkout activ.

Can anyone help me? I think the code is not correctly?

So far no one has been able to solve it

I will give the URL/Password → DM (Private Message)

Thanks
