Why does she hide our relationship on social media?

Anonymous
Been with my girlfriend for a year now. And I'm finding myself wondering why she's hides our relationship on Facebook, only a select few can see we are in a relationship. There is no photos of me on hers, she uploaded one of us to instal last year but that it? We do loads together. I don't upload loads of pics but my dps are of us. I wouldn't normally care but I feel like she's hiding out relationship from people. All her close friends and family know about us and I have met them all loads of time. Should I be worried? How should I approach asking her about this? Last time I asked her she said it's only social media, there's no need to worried about it.
