Multiserver administration - passing maintenance plans to clustered instances

SQL Server 2019 MSX/TSX environment. TSX servers are clustered instances. MSX is not. There is a SQL integration service on each of the nodes in the cluster. I create a maintenance plan on the MSX and when i try to push it to the TSX i get this error: >Message Failed to import Maintenance Plan 'MaintenancePlanMSA' from MSX: Microsoft.SqlServer.Management.Sdk.Sfc.EnumeratorException: Failed to retrieve data for this request. ---> Microsoft.SqlServer.Management.Common.ExecutionFailureException: An exception occurred while executing a Transact-SQL statement or batch. ---> System.Data.SqlClient.SqlException: Parameter 0 is incorrect for this statement.

The funny thing is that the job, under the maintenance plan, appears on the TSX. When i create a standalone job and push it to the target, the job appears on the TSX(?!). Hope someone can help. Thank you in advance.
