The side mirrors are not properly adjustable

What is your question?

When after adjusting one mirror, I try to adjust the second one, both of them moving in the position, which is not useful. Same with the reverse order. Seams like they both interconnected and cannot be operable individually. Same time will not stay as adjusted.

What makes this problem better or worse?

No noticed the difference
