Migrate/export

Hello and sorry if this thread is posted in wrong topic and big images. I want to create an first person shooter game and I have some trouble with migrating character + weapon from DEMO, in my own project. In other words, I managed to migrate and setup the character ( hands ) but the animation did not copy well, I can’t use animations from " Use animation blueprint"

.
But I can set a single animation from " Use animation asset ".
.
And about the weapon, I can not use at all. There are no component related
Could you help me guys?
