Aria Automation 8.x
When the yaml of a custom form is edited outside the UI and imported back then subsequent changes to the form in the UI may leave remnants of the previous configurations done outside the UI leaving inconsistent content.
This results in Service Now selecting the incorrect datatype for the fields when content is synced.
To resolve the issue:
1. Export the affected custom form
2. remove the value list section from the relevant field in the yaml.
3. Import the corrected yaml as new custom form in Aria Automation
4. Perform service now sync
Validate it no longer shows as drop down in service now.
