Editing any field in the attribute table causes a double-type field with a comma-based domain (configured under French (Canada), decimal (,) regional settings) to reset to <null>.

解决办法

Only edit the attributes in the attribute pane, not in the attribute table.

Change language settings to:

• Region : "English (Canada)", Decimal : point "."
• Region : "English (Canada)", Decimal : comma ","
• Region : "French (Canada)", Decimal : point "."
