Krusader panel/side activation

[Don Escamillo]

Mint Mate, krusader installed, set with two sides, each side has a tree panel and a list panel.
The problem is that clicking on a tree panel does no implicitly select its side and its corresponding list panel.
For example:
1, Open krusader, two sides, each side has a tree panel and a list panel.
The active side's list panel has a blue header. Let's say the right side is the active one.
2. If I click on a folder in the right-side tree panel, its contents will be shown in the right-side list panel as it should be.
3. If I click on a folder in the left-side tree panel, its content will be shown in right-side  list panel, not in the left-side panel.
This means that when I click in a list panel, its side becomes active, but when I click in a tree panel, its side will NOT become active.

Is this by design?

Should not clicking in a tree panel select implicitly its corresponding list panel?

Can it be changed by some setting?

Just trying to make the description of the problem clearer:

1. Open krusader, two sides, each side has a tree panel and a list panel.

2. Click inside of the right list panel - its side becomes active and header goes blue, no matter if the side was active or inactive before the click

3. Click inside of the left list panel - its side becomes active and the header goes blue, no matter if the side was active or inactive before the click

4. Click click on a folder in the tree panel on the inactive side - its side DOES NOT become active and the header does not go blue. As a result, the active list panel, which is the list panel on the OTHER side, will show the contents of the clicked tree panel folder. This is weird - click on a folder in the tree panel on one side, its contents is shown in the list view on the OTHER side.

Can this behaviour be changed by some setting?
