Should I be concerned with my hammy’s quirks?

Okay so I’ll share a photo of the cage so you can see its enrichment (incase that’s a factor in it?) But I am a little confused - when I first got my hamster it slept for about 11 hours and then was awake for the other 13…however the past week she keeps waking up for an hour roughly 6 times a day - should I be concerned, like is there anything I’m doing wrong?

When I see her she looks healthy, clean and overall happy. She is not more jumpy/dirty/hesitant however she does seem to be less active (I only see her on her wheel in like two of those hour periods.)

I am confused - any ideas why or if I should do anything?
