Show complete OTA channel numbers?

The channel list and the channel guide do not show the channel number for OTA digital channels. So instead of four sub channels 32.1, 32.2, 32.3, 32.4 I get four entries all showing ’32’. This is not caused by my backend (NeXT) because Estuary skin does show the correct numbers. Rapier 10.4.1 for Krypton

How do I tweak the display format to show the correct channel?
