This could be because you haven’t re-published the updated amendment in Lawmaker.
If an amendment has been withdrawn before it appears on a Marshalled List, you will need to republish it as it won’t automatically get included in a subsequently published list. Re-publishing the amendment will push the update to a central repository accessible to LegHub. As long as you have scheduled an update for this project stage in LegHub, then you don’t need to do anything further for the amendment to appear updated on the website later that evening.
