Automatic deferred revenue not working properly

I’ve created a sales invoice with a deferred revenue account, but I could not find the spit of revenue for each month (even for sales invoices or purchases) in General Ledger
Only Total Revenue appears, but no individual value for each month is shown in the report.

I checked the
“Automatically Process Deferred Accounting Entry” in " Accounts Settings"
also checked the:
“Book Deferred Entries Via Journal Entry”
and “Submit Journal Entries”
I tested with different options (automatic or not, expense or income…)

I’m using version v13.21 of erpnext.

Anyone can help?
Thanks in advance.
