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?
