I tried to import an unmanaged solution file. The import always failed and didn't give any error messages.
I sorted the Status column in the importing solution window, and found that all entities/forms/views/charts were fine. However, all items with type = process/process activation (customized) didn't have any value in "Date Time" and "Status"
columns.
Any idea how to fix this?
I have also added a screenshot for your better understanding.

Thanks in advance!
