Only My Skill Tooltip Is Strange

Summoned to a place called the “Tower of Struggle,” I was introducing myself to ‘players’ I had never met before and discussing the ‘system’ when― “…What’s that about the Smash option?” “Smash? Hold on a sec. Let me check it again.” I realized that my status window was different from the others. “It says I can hit the opponent hard and deal 150% physical damage.” [Smash] [F] [Hits the opponent hard, dealing 『1,521%』 physical damage.] “And what about First Aid?” “…It says you can wrap a bandage to restore 50 HP. But how much is 50, exactly?” [First Aid] [F] [Wraps a bandage to restore 『503』 HP.] Why is only my skill description strange? Is it a bug?
