Pt(s) | Mn2+(aq), MnO4-(aq), H+(aq) || H+(aq), IO3-(aq) | I2(s) | Pt(s)
Pt(s) | Mn2+(aq) | MnO2(s) | H+(aq) || H+(aq) || PbO2(s) | Pb2+(aq) | Pt(s)
how come the first one has comas within cell notation but not the second one,

Are you sure of the second one? It appears to have two salt bridges. || and ||
oops, the second one should be
Pt(s) | Mn2+(aq) | MnO2(s) | H+(aq) || H+(aq) | PbO2(s) | Pb2+(aq) | Pt(s)
but can you clarify the comma one
Pt(s) | Mn2+(aq) | MnO2(s) | H+(aq) || H+(aq) | PbO2(s) | Pb2+(aq) | Pt(s)
but can you clarify the comma one
Commas separate multiple species in the same phase. The single bar is used to separate phases.
