I see icons is in new maps now like this one:

In another post regarding this problem are you asking the person to take the icons in /uploads/2019/05/icon2.svg..
So my question is.. maybe you forgot to change the path to these icons in the themes.

How do i import them or where can i manually upload them?

BTW: The AMP problems were sold after i imported 3 different times.
