How is Path of Building expected to behave?

I've used POB before to calculate the effects of forbidden flesh and flame. Weird enough, when I tried to use it with unrelenting flesh and flame in my RF chieftain build (which is clearly a marauder class), it keeps on saying that marauder class unmet.

How does Path of Building behave?

It says that the forbidden flesh and flame requires marauder class.

How to reproduce the issue

Just paste an unrelenting flesh and flame in the items tab and try to use it with marauder class or any RF chieftain pob available.

Screenshots

Reproduce the issue with the linked RF Chieftain build and an Unrelenting Flesh and Flame item in the Items tab. Trace the class requirement validation for the item; done means a Marauder/Chieftain build no longer reports the requirement as unmet.
