Form 2210 Underpayment Tax Penalty Worksheet

Form 2210 - Underpayment Penalty Worksheet doesn't seem to be bringing in estimated tax payments listed on the Tax Payment Worksheet into the appropriate due date installment section.  The first installment due date is 7/15/21 on the Underpayment Penalty Worksheet. I have a Tax Payments Worksheet that lists four estimated tax payments made, including the first on 4/15/21 and the second on 6/11/21.  Only the first payment is included in the 7/15/21 installment section on the Underpayment Penalty Worksheet.  (The remaining payments appear in subsequent installment due date sections of the Underpayment Worksheet.)  This is creating an underpayment calculation for the 7/15/21 installment, when actually more was paid in estimated tax prior to 7/15/21 than is shown as the required minimum installment due on 7/15/21.  Any comments or suggestions?
