Hi,
Do you have any performance issue when you add the 4th 1820?
Please make sure there is no loop in your network and please update the devices to the latest version in WEB:
https://techlibrary.hpe.com/OfficeConnect/?SKU=J9979AIf the above is done and if you still have any issues you could log a ticket with the local TAC team providing them with the diagnostic logs.
Regards
