How is Lag Finish calculated?

Morning all, I've got an activity whose predecessor has completed but in the predecessor tab it says 'lag finish' and it several days later pushing out a date artificially. I can't seem to find any explanation as to how this is calculated. Screen shot below of a similar item. I've checked all preceeding activities and there are none outstanding and none suggesting the date as 6th March.
Thanks in advance for any assistance.
EDIT - found the issue kinda, so the activity above completed on the 3rd the data date is the 5th and that is what pushed my activity out to the 7th, I don't understand why it couldn't start on the 6th.

It looks a result of
It looks a result of Out-Of-Sequence activities. P6 default calculation of relationship lag is based on "Predecessors Calendar" which can be change on Scheduling Options Calendar for scheduling relationship lag to:
1. Predecessors Activity Calendar
2. Successors Activity Calendar
3. 24hr Calendar
4. Project Default Calendar.You can check which of this option is set on your Scheduling Options so you can identify what is pushing the activity and why? specialy on Out of Sequence conditions.
