Doesn’t roll? But spins around

So my 7 month old (second child), I’ve seen her roll very few times. But the girl can spin. I’ll put her head towards the “head” of the crib on her back at nap/bed time and come back and find her either having done a 180 or laying cross ways but still on her back. Then same with tummy time: I’ll face her one way. Come back and she’s spun and facing another but is still on her tummy. She sits up on her own for the most part and when you hold her upright, taps her feet or attempts to jump. Absolutely loves the door hanging jumper seat and exersaucers at daycare. Just no rolling. I plan to address it at her next check up but idk. Something in me became suddenly concerned that we are behind. I already know we’re a little behind on solids but suddenly became paranoid about her motor skills.
