15% Visual Bug?

I just saw this on Basil =O Common sense tells me its only a visual typo (similar to 30% shield ma's description saying its 50% successrate) and it will end up giving def when it passes, but another part of me wants to believe it actually adds wa due to Nexon's notorious programming bugs.

Anyone scrolled a 15% overall str from the butterfly scroll-trade event can confirm this? It's already in basil, so no need to try and keep it on the lowdown ;3
