Spells: Quiver of Marr 0% WR?

[Austianity]

I remember the Mage Spell: Quiver of Marr, having 50% WR making it the second best archery haste item apart from Fleeting Quiver.
On P99 the Quiver of Marr displays 0% WR.

I looked at patch notes to see if there was a time when the WR % was implemented or if it was changed but couldn't find anything. Just seems like it always had 50% WR?

Apologies if this is already known or posted in forum somewhere etc. I tried looking it up in forum and in patch notes before posting and couldn't find any info.

Thanks!
