Hi Jandoval,
I don't think that change in the nominal amount (via capital structure) should impact the installment repayment amounts (Flow types 1130 in your case) in the deal - please verify your conditions ('Goto' -> 'Conditions') - you can find all valid conditions the and also definition of each of them (by double-clicking).
if you are not sure, you can attach the screenshot of that window.
Kind regards,
Renatas
