ZOHO books - import statement, why there only one line item be accept?

ZOHO books - import statement, why there only one line item be accept?

When I import statement, zoho always says "statement line(s) that are ready to be imported ( 1)", although there are more than one line in my statement!!! There should be more than one! if I click import, than there only one line from my statement will be posted, the others are ignored by ZOHO.

Do any one know how to fix it?
