The extreme Population I material in a galaxy ( dust, molecular hydrogen, OB stars, etc) behaves very differently from the mass-dominant component of old and/or intermediate -ages stars .
Particularly in dwarf galaxies, this young component can look highly chaotic and entropic and not entirely symmetric. This is "situation normal " for a star-forming dwarf galaxy .
Thus, the spiral structure in this galaxy is conceivably quite normal.
However, young Dana, as you are a bright boy, maybe you can disprove my hypothesis .
In a way, the "bun' of old stars that underlies the 'sprinkled cinnamon' of young stars, is more anomalous than the spiral component of this galaxy, as it looks to be a Dwarf Spheroidal Galaxy, that co-exists with a spiral galaxy ( or spiral component)
As Dana does , I suspect a low gas content and a low Star Formation Rate , in this galaxy .
So Dana's hypothesis that the pretty sprinkling of blue stars ( the Cinnamon!) is a transient phenomenon that is part of the settling down of this galaxy towards a quiescent state, has merit
