Got the same errors but finally found a work-around.
If you imported data directly from CRA/RQ, there are probably errors from there.
Solution :
- Select Forms Mode;
- Go to all slips applicable in your file;
- For any numbers in red, you must override (F2) and put "zero" or the correct no;
- Validate if all numbers are blue;
- Check if new numbers affect your return, if not save it and problem solved.
