Mix results after using star removal

When processing my DSO photos, sometimes I get great results after star removal (I am using starnet2) and sometimes it is just terrible.

For example, M42 (6h total integration, bortle 3) looks pretty good



But Heart nebula (7h total integration bortle 4) and Soul Nebula (4h bortle 4) looks not so great




All photos used the same equipment:

Redcat 51
Filter Optlong UV-IR
camera ZWO ASI 294MC

Could you please try to explain me why this happens? I really have no idea.

Nothing is happening, the stars have been removed (there is some residue in M42, tbh).

Try removing stars after a careful stretch and noise reduction.
