Discrepancies on amendment roll call votes

[amickael]

I've noticed that the roll call votes for amendments on HR2500 from the 2019 session of the 116th Congress seem to have some discrepancies? For example, on roll call 460 the amendment author is "Amash of Michigan Part B Amendment No. 50", however the question text is "On Agreeing to the Amendment: Amendment 33 to H R 2500". Which one is correct? Was this the vote on amendment 33 or 50? House Clerk website seems to suggest that this is for amendment 50: https://clerk.house.gov/Votes/2019460

Thank you.
