Copy / Paste Data from one sheet to another.. get duplicates



Hi Forum,

I created a List, where a Excel formula randomly assigns “Mitarbeiter” to “Zuordnung1 & 2”.
With a “read cell” and “read color” activity, I copy the data and transfer it to another sheet (“Tabelle2”)

As you see, in the first picture we have the numbers 5,35, etc. in the beginnging (Zuordnung1), and for Sheet2 4,13 etc. It should be the same, since they´re copied row by row.
I use a for each activity to iterate through it row by row, copy it and write it row by row.
Another strange error is, that some values got duplicated (yellow marked), but they exists just once in the original table. Anyone has an idea whats wrong?

Thanks a lot!
