Xbox 360 NPC Selection Glitch

Suddenly when I hover over an NPC, it does not say (A) Talk Lydia, for example, it just says the NPC's name, such as (A) Lydia. Same with my horse, it does not say Ride, or Search when looting. When opening a door it still says (A) Open Sleeping Giant Inn, for example. Seems to be working fine I'm just wondering what may have happened and how to fix it. Thanks.

Seemed to fix itself right after I posted this. Nevermind. Although still I wouldn't mind knowing what the cause was if anyone still wants to answer.
