Terrain Brushes not updating when settings are changed

This used to work before the U5 update but every since then, I am unable to get the terrain brushes to work properly. If I change settings on a terrain brush, the changes won’t take effect until I select another object, then select the terrain again. After that the brushes have the new settings. This makes it extremely difficult and tedious to work. Any idea as to what might be causing it?

Solved. Apparently the Inspector window was bugged out after update. Closing it and opening a new one seems to have fixed the problem.
