Information not avaliable on CMDB

Information not avaliable on CMDB

Hello, 
We used to have a workstations' information available in the CMDB, but after the update to the version 15.1 15100 we can't seem to be able to see it. And I don't know if it is related, but I got the following message when opened Service Desk (On-premise)
“The CMDB V1 APIs, the asset CI, and the workstation CI that are deprecated but still in use require action.”
And following the More information, we don't know what it means.
