Status Det on Mypay

I medically retired from the Army on August 23,2025 and got my “last” paycheck on August 26th for $1,907 which is far less from my normal paycheck of $2,535. My pay is saying i have a Status Det of $3,263, what does that mean? will i eventually receive that amount? i also didn’t receive my clothing allowance for the month of August.
Also if anyone can explain what “New Netpay” means on the retiree mypay account, thank you

Any information helps!! Thanks!!
