Australian PR 190 Application - Employment inputs

My ACS Evaluation:

But in my EOI:

In my EOI, I made the mistake of giving the start date as 05th March 2015 instead of 06th March 2015. Can I keep it as 05th March 2015 in immi application like my EOI or change it to 06th March 2015?

How will this impact my application?

Unless the total points change after editing the EOI, it should not affect anything.

I have also not mentioned my employment period of 10/12 till 4 March 2015 in the EOI as I am not claiming points for this.
Should I add the missing detail in IMMI application and select no ?

How will this impact my application?

I already have NSW invite so cannot change EOI.
