Hi there, riverwa. Let me help you save your checks successfully.

When recording multiple entries using the Batch transactions feature, be sure to input all required information, particularly in the Bank Account and Category fields, to prevent unexpected results. To continue, hover your mouse over the red mark on the table and promptly save the data again.

I'm adding this screenshot as your visual reference.
