Import of Items

Hi all. I'm trying to import items in using the export template. It shows the progress bar reaching the end but the save button is still showing the rotating 3 dots & not items show. I've gone & left it overnight but still not showing my items. I have tried putting less items on the excell sheet, but with no success. I have 83 items in total.

Seems as if I solved the problem... Patience first. Then only 20 items at a time...
