OK here you go:
FLKC is Fine Learnt Knock Correction - Negative is where it is pulling timing, it can only be positive when IAM is less than 1 and is where it is attempting to add timing back in. If successful then the IAM will increase. This is stored in load/RPM regions so if it has added or removed in the past then this will resume from the last stored value.
Knock Correction - Usually known as FBKC (Feedback Knock Correction). This is at lower loads, is as it says and is instant feedback. Only FBKC or FLKC can be active at any one time.
KC Learn - This is the ignition advance map multiplied by the IAM plus the FLKC value. Or in simple terms, how much ignition advance is being added. Not a useful logged parameter IMO.
IAM - If the default value is higher than the IAM at shutdown, then the IAM moves to the default value at startup. The IAM can only increase under certain conditions so it not increasing is not necessarily a sign of an issue. Only if it drops (and TBH if it drops by a reasonable amount) or never reaches 1 would I look at addressing it. If you're happy that you get regular good fuel, I would set it higher than 0.7 and see what happens.
