The import confirmation email lists rows as "migrated" although data are missing.
As I can see in the pictures this will be a new feature instead of a bug. We will add this new options as soon as possible. I will close this issue because is not a bug. If you want you can open a new post in "Feature request".
Thank you and sorry for the incovenience.
When you import data from SM to DS, it saves the queries in the DataslayerQueries tab. Once the import has been successful, you will need to go to the tab to refresh the imported queries. (i.e. just clicking the "Import from Supermetrics" option will not be enough to show the data. You need to refresh the queries).
If this is not the problem, it is not clear what you mean by "comparison dates are ignored". If you can explain it in detail (maybe with some screenshots) I would appreciate it!!
Let us know if you need anything else!
