Menu block goes crazy after 4th level

Question

When I click on a 4th level link of a Menu block, the 3rd level disappear. This is the menu:

• Services
• • Accommodation
• • • Building A
• • • • Apartment 1
• • • • Apartment 2

I have 3 blocks to show this menu:

1. 1st level block (Starting level 1st, max depth 1): is ok
2. 2nd level block (Starting level 2nd, max depth 1): is ok
3. 3rd level+ block (Starting level 3rd, max depth 9): it's not ok

When I click on a third level link (Building A) the 3rd block shows:

• Accommodation
• • Building A
• • • Apartment 1
• • • Apartment 2

but when I click on any 4th level links (i.e. Apartment 1), the 2nd level link disappears and it shows:

• Building A
• • Apartment 1
• • Apartment 2

I need to see the third level links even if I click on the 4th+ levels. What I need is this:

• Accommodation
• • Building A
• • • Apartment 1
• • • Apartment 2

Thank you.

Solved. In the menu block configuration, Advanced Options, I checked Make the starting level follow the active menu item.
