Drupal 8.x

I have multiple language of site. with disable language module https://www.drupal.org/project/disable_language. I disable two language EN and DE. rest RO (Romania) and RU(Russian) language are enable

I am using the following code in the templates of the home page of my site, to make the display mode frontpage_tasks for the current user's account. It works perfectly :

{{ drupal_entity('user', user.id, 'frontpage_tasks') }}

I want to make the same display mode for the current user's stores and groups. I tried the code below but it doesn't work :

{{ drupal_entity('commerce_store', user.id, 'frontpage_tasks') }}

and

I am trying to change style on the site branding and links in the footer. But when I look in page.html.twig it sees {{ page.navigation }} and {{ page.footer }} only.

Where are these set? Search inside the theme files did not find.

Thanks.

In the menu at the top left of my site, I have accordion menu.

I want to rotate the "+" icon when the accordion is open.

In the green buttons, at the top of the menu, I want to make a roration of the "^" icon when the accordion is open.

The rotation works, but the icons do the rotation, even though I didn't click on the accordion.

Why is it not working properly ? What is wrong with my CSS ?
