Breach Ring Dex Roll Bugged

So whenever I try removing my T1 life roll on my breach ring even with a Omen of whittling AND a Omen of sinistral erasure it trys targeting the T8 SUFFIX dex roll. which shouldnt be possible because the omen of sinistral erasure states that only prefix's will be remove, would greatly appreciate help to fix this.
