Can't discard file if it's locked

[PavelLaptev]

Problem:

1. I changed file A, and this file was changed on the branch A.
2. I committed this branch and pushed the commit.
3. I create another branch B (default branch) and start work on another things. But then I changed file A again and changes for this file appeared on both branches A and B

The problem is that I wanted to have changes for this file either on a default branch B and then move it to another branch I want, or it appeared on the branch A if it's locked to this branch

How I tried to solve the issue 5. I tried to move file A from the branch B to A — no luck 6. I tried to discard changes for file A on the branch B — no luck

I attached a short video:
