[16.0] Odoo Error While using Account Chart update - Expected singleton

[SIC-brunorocha]

Hello, I´m new to using the module, but I get a Odoo Error when using it.

Module
account_chart_update

Describe the bug
File "/home/odoo/src/user/account_chart_update/wizard/wizard_chart_update.py", line 621, in find_account_by_templates
return result.id
File "/home/odoo/src/odoo/odoo/fields.py", line 5090, in get
raise ValueError("Expected singleton: %s" % record)
ValueError: Expected singleton: account.account(18, 20, 220, 222, 36, 38, 40, 236, 242, 42, 44, 46, 244)

To Reproduce
Open Update chart of account, select a chart template, press next.

Expected behavior
I believed is expected to move from Configuratioon, to Select Records To Update State.
