Small error importing data sets

Hi all,

We are experiencing an rare error in dhis 2.26 importing data sets (from another dhis2 instance with the same version). All the import goes correct but the data elements linked with the data set don’t have the categories combinations (even though the category combos are also imported in the import process).

The data elements of one data set just after the import looks like that:


And for example in the design custom form screen we can only select the data elements (without category combos). Then to solve this problem we need to remove all this data elements from the dataset and add again, then the “(default)” dissappear and all works well.

Any idea on that, we are in the last build of DHIS2 2.26.

Kind regards,
