Hi,

I’m trying to create on the server:  
[https://play.dhis2.org/2.30/dhis-web-maintenance/index.html#/edit/otherSection/predictor/add](https://play.dhis2.org/2.30/dhis-web-maintenance/index.html#/edit/otherSection/predictor/add)  
Predictor for autofill data element that has categoryCombos with data from past periods.

The documentation says:

But when after select the Data Element, does not display the Output category combo dropdown:

Did I miss something or this have to be reported on Jira?

Thanks for support.

Hi @jomutsani and @Emma_Kassy, I can confirm this bug in 2.30, 31, and 32. Can you please create a bug with steps to reproduce? Then, I’ll push it to the devs to fix
