It looks like secondary effects against a substitute will still apply if the move breaks the substitute. For instance, if I break substitute with scald, the pokemon still has a chance to be burnt. This should not be the case.

Hello, thank you for reporting this bug and after some testing myself I have also noticed that moves like scald, ice beam, flamethrower, ect (any move with a secondary effect) can affect the substitute move if the sub breaks the same turn.

I used 6 Archeops with oran berry a level 1 with substitute and a npc with 6 Squirtles using scald at level one with a leppa berry and it does in fact inflict the scald burn status.

I assume that any move with a secondary effect has a chance to. This isn't too much of a game changer because depending on the move it only has a 10% chance to inflict it but it is still a bug none the less.

Moved to internal.
