Data from database appear in vuex-store state but can't get it in template

Need help!
I got problem with displaying object data state from vuex store to my template.
My App.js:

This is my Store(mutations/actions):

I get records from database by axios and pass them to my state. And it works when i console.log:

But i get empty array - [] when i want to display it in my template like this: {{ authors }}
My template:

Also I can print any predefined state from store but not one that i get from database. Is it problem with “dispatch” ? It looks like something empty my data when i pass it to template.
Thanks in advance!
