Thanks for your post and patience. Sorry to hear that you’re facing this issue which isn’t clear why this is happening, however, I see you are referring to Event Reports so may I ask which version of the DHIS2 instances are you using? It’s possible that this issue has been fixed in later versions.
I couldn’t find a specific reason or clearly documentation situation when this happens; however, is possible that this issue is somehow similar to: Possible Bug in Analytic Tables [fixed]?
How are you running the analytics tables export? Is it scheduled and does it include all the data? Additionally, would it be possible to share the configuration of the ‘program indicator’ and the ‘enrollment program indicator’? Finally, do you think you would be able to reproduce this issue on any of the play.dhis2.org instances?
Sorry if I’m asking to many questions. Thank you!
