Hi @weird_guy,
How are you sorting the first visual? It looks like it may be sorted by ‘Convert to EUR’ descending. If you remove that field, you will no longer be able to sort by that so the ip_country will no longer have that field available to tell it how to sort.
If you left ‘Convert to EUR’ in your table, you can just change back to sorting from that field. If you removed it though, you can sort by an off-visual field:
