My date of loss on my ERB is different from my report date. Does anybody know why this is?

I recently re-enlisted for pcs to Fort Bliss with a report date of 10 June 2018, however i just noticed today on my erb in the date of loss column 27 Mar 2018. I asked my s1 personnel and they told me they had no clue why and they looked on the 162 and saw the same date as well but couldnt explain to me why. I would be happy to report early if thats the case however i feel its too good to be true.
