Oh, it's even better than that ... Challenge to Kasich's ballot status may be canceled by the clock - WaPo - March 10

Well reading through it it also says:
Phil Kerpen, a conservative activist who'd been watching the case with a critical eye, quickly tweeted that Rome bungled it.

“Looks to me like Kasich’s botched petition might stand because the Rubio supporter who challenged it botched the challenge.

So this tracks with what I checked today, and Kasich IS officially on the ballot.
