[[3.3.1] Can't set brim size]

Also, the version I was on is different than this posts version but, I have had the same issue previously. I am on 4.4.1

[[3.3.1] Can't set brim size]

I figured out how to be able to change this again. 

There is probably another way but, I just switched to skirt and then sliced the model. Then I switched back to brim and all of the settings were available and they actually created the brim width that I set for it.
