Steps to reproduce

1.  Use a content app with a column of long values
2.  Sort des Column

(See screen recording in attachments)

Expected results

The column would be sorted in ascending or descending order.

Actual results

Somehow it seems like the long values are handled as string values. But the outcome is not completely logical or explainable. 

Workaround

I don't know any workaround which would help here.
