When a recurring expense is added payable to a landlord, the expense will always appear on the original ledger it was created against.
If at some point you have Assigned the property to a difference landlord ledger, the recurring expense will still apply to the original ledger. If you want it to be raised against the new ledger, you will need to add a new recurring expense and delete the original.
When assigning properties to ledgers, please ensure you add new recurring expenses and delete any historic ones that are due to be raised against the old ledger.
