Runes and Sigils with Mislabeled Elements

It has come to my attention that there may be a number of runes and sigils that have their Elements (Pain, Potence, Enhancement, etc.) mislabeled.

For example, Superior Sigil of Icebrood Slaying is currently labeled as a "Control" Sigil. Not only is this an inconsistency with other Sigils of Slaying, which all have the "Pain" element instead, salvaging the above Sigil will indeed yield Symbols of Pain, instead of Symbols of Control.

Edit: It would seem that other mislabeled Sigils and Runes have been identified in this other bug thread by @"Cirian.8917" :https://en-forum.guildwars2.com/discussion/60515/sigil-crafting-element-symbol-mismatches
