Hi, When you create a file in krita, create a group. Put all layers en this group, save in psd, close Krita, open Krita, open the psd, Krita collapse the folder in single layer.
Thanks for the report. I can confirm the issue.

Fix psd layer info for single layers or groups Not writing the layer info when only having more than two children for the root layer causes loss of data if the first child is a layer group. Additionally, other layer properties such as name and opacity and more do not get saved.
