Sql-server – Issue with Table Naming Conventions and Policy Management in SQL Server 2016

In SQL Server 2012, I had a policy set to not allow spaces in a table name. However, when I use the same policy in SQL Server 2016, I get an error.

Here is the code for the condition:

DECLARE @condition_id INT
EXEC msdb.dbo.sp_syspolicy_add_condition @name=N'No Spaces', @description=N'No spaces in table names.', @facet=N'IMultipartNameFacet', @expression=N'<Operator>
  <TypeClass>Bool</TypeClass>
  <OpType>NOT_LIKE</OpType>
  <Count>2</Count>
  <Attribute>
    <TypeClass>String</TypeClass>
    <Name>Name</Name>
  </Attribute>
  <Constant>
    <TypeClass>String</TypeClass>
    <ObjType>System.String</ObjType>
    <Value>% %</Value>
  </Constant>
</Operator>', @is_name_condition=4, @obj_name=N'% %', @condition_id=@condition_id OUTPUT
SELECT @condition_id

Here is the code for the policy:

DECLARE @object_set_id INT

In SQL Server 2012 and 2014, this gives the expected results:

CREATE TABLE [test table]
(Id INT NULL)

Policy 'Table Names' has been violated by
'SQLSERVER:\SQL\LSRSQL07\SQL2012\Databases\test\Tables\dbo.test
table'. This transaction will be rolled back. Policy condition: '@Name
NOT LIKE '%[- .]%' AND @Name NOT LIKE '%[^A-Za-z0-9[_]]%'' Policy
description: '' Additional help: '' : '' Statement: 'CREATE TABLE
[test table] (Id INT NULL) '.
Msg 3609, Level 16, State 1, Procedure
sp_syspolicy_dispatch_event, Line 65 [Batch Start Line 48] The
transaction ended in the trigger. The batch has been aborted.

And if I run the following code, I get no error:

CREATE TABLE [testtable]
(Id INT NULL)

However, if I run any CREATE TABLE statement, with the policy enabled, on SQL Server 2016, I get the following error:

Policy 'Table Names' has been violated by
'SQLSERVER:\SQL\LSRSQL07\SQL2016\Databases\test\Tables\dbo.testtable'.
This transaction will be rolled back. Policy condition: '@Name NOT
LIKE '% %'' Policy description: '' Additional help: '' : '' Statement:
'CREATE TABLE [testtable] (Id INT NULL)'. Msg 515, Level 16, State 2,
Procedure sp_syspolicy_execute_policy, Line 69 [Batch Start Line 44]
Cannot insert the value NULL into column 'target_query_expression',
table 'msdb.dbo.syspolicy_policy_execution_history_details_internal';
column does not allow nulls. INSERT fails. The statement has been
terminated.

In SQL Server 2016, I cannot create any table, whether it passes the condition or not.

This is SQL Server 2016, SP1, CU3.

Any ideas on this?

Edit:
I am needing the evaluation mode to be "On change: prevent"
