Yup, that plan is delayed because after KAI and LM join, the C 103 design is still being developed so the program get longer than it should be.
The technology demonstration phase has also resulted with C 103 design. In 2015 KAI and LM join the program. C 103 design is later refined and become C 109 design which is bigger than C 103 but the shape is not really different.
Preliminary Design Phase was completed in July 2018 and it is the start of Critical Design Phase. In September 2019 there is CDR (Critical Design Review) and it shows critical design phase has almost been completed.

Talking about first part of KFX/IFX production yes it is started about 6 month earlier than CDR, but it is only a small part. So I think you are right.
This is part of KFX/IFX that is started to be produced in early 2019.
