Dragon Halls says boost Armor, shows Attack icon; Tinker's Cavern says boost Attack, shows Armor

Steam - Windows 10 Home
The Tinker’s Cavern monument says a boost of attack, but the icon shows armor. Also, the Dragon Halls shows attack, but shows armor. Likely the 2 had their attributes switched
I have not used the monuments myself, so don’t know what the actual boost is (I leave that to a tester who gets the Monolith Sigils for free)

Dragon Halls should boost attack. (4,6,8,10,12)
Tinker’s cave should boost armor. (6,9,12,15,18)

How often does this happen? When did it begin happening?
Since monument update.

Steps to make it happen again
Go to PVP - Buffs. 3rd monument Dragon Halls. Click on it. Go back.
9th monument Giant’s Hall for comparison. Scroll to get to it. Click on it.
