Document Understanding ML extractor not showing dropdown

[m.tan (Michael Tan)]

Dear community,

I am facing this issue with an automation I am currently working on.

When I run validation station, it showed the PDF and captured none of the data (to be expected right? since there isn’t any matches).

Studio version 2023.10.4
UiPath.DocumentUnderstanding.ML.Activities package version: was latest v1.31.2, I downgraded to v1.28.1 to debug, both version having the same problem

I have another main.xaml created using Studio 2022.10.13 and when I open with Studio 2023.10.4 it has the drop down list.

Any thoughts on this would be appreciated. Thank you!

Additional Information here. I added ML extractor activity in the previous code, the dropdown is not showing as well. Time to go back to previous version of studio I guess? UiPath’s fast and constant upgrading of product is a challenge to users.

Dear all, just an update. I revert to 2022 version and it worked. Now trying to do more isolation test to find out the actual cause of issue.
