Dynamo messes up the import from xlsx

Hello Ladies and Gentlemen,

I managed to make an export of parameters from Revit to excel via Dynamo. Everything exports as it should. However, when I try to import the data back into the Revit, it messes up my Mark and there fore the rest of the parameters. I cannot pinpoint the problem and was hoping someone here could help me out. I have the revit files and two dynamo files in the link below :slight_smile:

Any help would be very appreciated :slight_smile:
