VS019 on 09/08 and VS008 on 19/08 (Load Check?)

I don't know how to do this myself as I have only read it in passing. However I am flying both flights on the dates shown and currently the seat map is saying all of PE is sold out. I am in some seats in PE Row 31 and 34 Respectively which are okay but was hoping to change these on online check-in but with all seats seemingly allocated will I be able to change. (BTW its me and my partner and we would prefer two seats together in the 2-4-2 configuration i.e. the 2 in the 2-4-2)
Any help would be appreciated. ?|
