Forums Activity streams in menu should use friendly URLs

[Safety1st]

IPB 4.1.8.1.

 

I created custom activity streams under System → Streams:

 

Then I created friendly URLs for them under System → Advanced Configuration → Friendly URLs:

 

After that, I added new menu items under System → Menu Manager that point to created streams:

 

The problem is friendly URLs are not used:

 

 

Although they work. Please fix.
