There is a bug when you have a date column, enter an invalid date and then press Ctrl+D to delete the row. You get an Invalid Date error, the row disappears and the value then appears in the row above it!
I have attached a demo project. Simply run it, for the 1st row enter a value for code and then a valid date, go to the next row, enter another code but this time an invalid date, e.g. 'A', Then press Ctrl+D, you get an Invalid Date error, the row is deleted and then the date value for the 1st row changes to 'A'.
Hello Stephen,
I've replicated the behavior you meant and forwarded this issue to our developers for further research.
