I came here to see if this was happening to anyone else. My husband was MVP last year, and on 12/29, he reached MVPG. We noticed the same thing. I JUST booked a ticket for him for February, and it reverts back to MVP. He's earning the correct bonus miles, but nothing else. The CSA only showed him as MVP on the UPG list, not as MVPG and he He wasn't acknowledged by the crew for a beverage, when the 2 men next to him yesterday were. He sheepishly mentioned it to the FA, and showed his status on his phone, and she graciously obliged him the GnT. She also showed him, he wasn't showing as MVPG on their list on their inflight phone device.
