Confirmed, and it's a display bug rather than anything to do with the warp itself.

The "#r" and "#k" are colour codes — they're meant to turn the "[Lv.10]" part red and then switch back to normal. The main dialogue text already understands those codes, but the blue clickable option rows underneath it don't: they get drawn as plain text with no parsing at all, so any code sitting inside an option label leaks out as literal characters.

It isn't specific to the Magician Statue either — it'll show up on every option row that carries a level tag or a ticket tag, so the Warrior, Bowman, Thief and Pirate statues, the Dimensional Mirror list and the subway/ferry menus all have it.

The fix is to run option labels through the same text parser the dialogue body already uses, so the codes are consumed instead of printed. The warp works fine — it's purely the label that's ugly.

The '#r' and '#k' in 'Magic Library (Ellinia) #r[Lv.10]#k' are MapleStory's colour codes — they're supposed to turn the level tag red, not be printed. The dialogue body text runs through a formatter that understands them, but the clickable menu rows were drawn as raw text, so the codes leaked onto the screen. The rows now go through the same formatter, so you'll see 'Magic Library (Ellinia) [Lv.10]'. This was never Magician-Statue-specific — every level-gated or ticket-gated travel option had the same leak.
