Need Help Resolving Marketo Record Update Issues

Happy Friday Team! I'm trying to run an enrichment for Marketo records. I have a webhook set up, so records are feeding into my Clay table. I subsequently run enrichment waterfalls and run an "Update Record" enrichment to push the field updates back into Marketo. However, I'm not seeing the values populate in Marketo...despite seeing a confirmation that the push was successful. Can you please help?
