Problem with menu (only more)

Hi, I have some problem. When I on some of modules my menu was broken, look at screen:

Wiecej is more in polish language. I want to see all modules on top, but now I have only More and drop/down menu.

How to change this ?

Try to alter the following settings:

Dolphin admin panel -> settings -> templates -> settings 

Number of main menu tabs visible to members outside of "more" tab

Number of main menu tabs visible to guests outside of "more" tab

When I set Number of main menu tabs visible to members(/guests) outside of "more" tab: to 0,1,8 or 20 is still more - any fix about this? When I set for ex. 4 i have 4 empty cells and "more" with all modules:

I have this problem on all themes.

This is screen of settings in admin panel:

Can't reproduce the issue, it maybe you have some modification or 3rd-party module which cause such problem.
