Hi @Tangy
What version of dhsi2 are you using? Is there a way to reproduce this issue in any of the play.dhis2.org instances?
Could you check if this fix (How to fix strange or incorrect icons in Maintenance) would solve the issue? And please make sure to clear the cache afterwards.
Using the Data Administration app → Maintenance, select Clear Application cache and Reload apps, and use the Browser Cache Cleaner app to clean the cahce. To ensure it’s not a cache issue, please test again using the Guest mode in your browser.
Thanks!
