WP 8.1 on Nokia Lumia 925 - WiFi disables cell service

Wondering if anyone else has this particular problem... I suspect it is linked to the WiFi calling that is enabled when connected to a network. I cannot send/receive messages or calls, or get any cell service (Although it still shows bars) when connected to a WiFi network. Not really a problem, since I barely use WiFi, but it's still strange.
