Please explain your issue is in as much detail as possible.
When you reform a religion, every time you select a feature that gives you levy, attack or similar modifiers, it overwrites previous features that also altered those modifiers. The features from your base religion (say, Germanic) may get overwritten by the selected nature (say, Unyielding), which may get overwritten by the first selected doctrine (say, Unreleting), which may then get overwritten by the second selected doctrine (say, Animistic). There is even the weird case of Tengri, where the modifiers from the base religion get overwritten by the modifiers from the religion’s special doctrine.

Steps to reproduce the issue.
1) Reform a religion, selecting multiple features that alter unit modifiers;
2) Verify the resulting unit modifiers.

This is a feature, not a bug. IIRC, the game even warns you when you select two doctrines with competing modifiers that one of the unit modifiers will be overwritten. This is incorrect, I checked in-game. See https://ck2.paradoxwikis.com/Pagans#Reformation_in_Holy_Fury for a concise explanation:
'Pagan religions retain some features when reformed, regardless of the features chosen during reformation. However, a religion can only have one "unit modifier", so offensive pagans will lose levy size and other bonuses if they select a reformation feature that adds a competing "unit modifier".'

Interestingly, Urloc the Great did show that Unyielding Nature works with Tengri's Eternal Riders doctrine last month in the 33rd post of this thread https://forum.paradoxplaza.com/forum/index.php?threads/ideas-for-fun-pagan-reformations.1333616.



EDIT: After some investigation, my previous comment of it being a feature, not a bug hinged on the fact that there was some documentation that they were not supposed to stack. The only documentation I found is from the wiki, which cannot be considered an authoritative source on its own.

Thus, this is definitely a bug, but it might be simply a tooltip bug.
