Not being able to see data elements in Capture app (Event Program)

Dear DHIS2 community,

We have a serious issue with the new Capture app in version 2.34 - not being able to see the Data Elements and Sections for an Event Program. Therefore we cannot capture data or see existing data (we only see event date and basic info). See the screenshots below where sections/data elements are just not displayed. The program was created in version 2.28 and it worked great until we upgraded to 2.34 (worked fine also in 2.29 and 2.31.8).
Additionally, in the Progra settings - we switched from SECTIONS to BASIC, but still, no data elements appear in the Capture app for this Event Program.
