Closed captions missing from NHK World

Closed captions, available until about 10 days ago, have gone missing from the York PA system channel 242, "NHK World" feed from Maryland Public Television. MPT's Chief Engineer emailed to say "I have verified we have captioning ... [if] you [are] still having an issue with NHK ... it will be on the Comcast end."

Could someone look into this and sort it out please?
