LCB on a Pokemon that I wasn't chaining?

I don't know if this is actually a bug, but I just hatched a random melan Duraludon that has +LCB as a part of it's timeline. I'm currently chaining Ruffwool, not Duraludon. I double checked to make sure I didn't accidentally break my chain, but I did not. Is this suppose to happen? This is the Pokemon in question.

Is it okay to bump this now?

Huh. Turns out the LCB actually bypassed the check that it was actually the thing you were chaining! So it did actually buff your Melan chances even though it wasn't your hunt! This has been fixed.
