Multiselect Dropdown Missing Values After Request Submission

Hi all,

Has anyone experienced an issue where a required multiselect dropdown field in a custom form fails to save selected values when it's shown conditionally (e.g., only appears when another field = “Yes”)?

In my case:

• Field A = Yes → reveals Field B (multiselect dropdown)

• I select values in Field B

• After submitting the request, Field B appears blank, as if nothing was selected even though it's marked required

Other required fields are saving correctly, and the logic to show Field B works it just doesn't retain the selected values after submission.

Any insights or recommendations on how to address this issue would be greatly appreciated. Thank you!
