Why is my console locked to 96kHz?

My PM5D is receiving digital audio via MY-slot and locking its word clock to the slot. The incoming digital audio is 48k but the console is locked to 96k. How do I change it to 48k?

Please go to Word Clock screen and select the MY-slot as a clock source. Then, change its Input/Output Format of the slot from "DOUBLE CHANNEL" to "DOUBLE SPEED". In a few seconds, the console will be locked to 48k.

All 96k capable products, such as DM/0 series, DME series, and PM5D, may have this issue.
