Duplicate a bill not working as before after UI update

Is anyone experiencing that duplicate a bill is not working like it did up until last week?

Use Case:
"As an accounts payable admin, I want to be able to copy a bill and use for multiple vendors so that I can save hours from inputting identical data for multiple vendors."
1. Save Current Bill
2. Select Duplicate from Bill Line Item Menu in Bills OR Select Copy at the bottom of the open bill that you want to duplicate.
3. The bill is copied exactly as the current the bill. THIS PART WORKS.
WHAT BROKE LAST WEEK:
Scenario: The user has many employees that use the exact same bill for the week, for example: Per Diem Payments that have two lines for each day and all have a project associated to each line. Time consuming to create.
1. The user would like to change the Vendor name only on the copied bill.
THIS WORKED UNTIL LAST WEEK. You would get prompted. Do you want to keep existing data from previous bill for new vendor? Yes or No. Hit No and I had the bill all created for the next crew member.
Now it doesn't prompt and it autofills with new vendor's previous bill with about half of the fields missing.
This is taking me SO long to do now. Please fix this back to the way it used to work.

I already left feedback. I want to know it this is really being looked at.
