Submittal Date/Time missing in Content Collection

I’ve created a Velo form that works perfectly except that the primary field Submission Time remains blank in the content collection after the form is submitted.

I tried setting up a text field as a date and time field and link it to the Submission Time in the Content Manager dataset, however after doing that the field remains blank in the dataset . If I repeat this for the Created Date or Update Date fields, they appear correctly but for some reasont it doesn’t work with the submission field. . Any ideas how to get it to link and show up?

Hello! Could you share your code that is updating the content collection? It should be easier to tell what is up that way
