Hi Michael,
The software version details are usually pushed by SAP Host agent and are automatically updated in the above screen that you have provided.
If you have updated the Host agent, ensure that the latest version details are shown here :
Solman_setup -> Managed System -> Host Tab -> Select the host and choose Show details -> check the Status for host is GREEN and below details are shown (SAP Host agent version 181 is displayed here)
SAP host agent version 181 is the latest available now; so you may try to update again and check.
Hope this helps.
Thanks & Regards,
Nisha
